      APT STATUS REPORT -- 2nd August 2004
      ==============================


      Satellite Frequency (MHz) Status Image Quality

      NOAA 12 137.500 on good
      NOAA 14 137.620 off
      NOAA 15 137.500 on good
      NOAA 17 137.620 on good


      NB. There are no Russian Meteor or Okean satellites transmitting or able
      to transmit APT.

      CHANGES SINCE LAST REPORT.
      NOAA 12 APT (VTX-1) switched back on (see Note 3).

      THIS WEEK'S POSSIBLE EVENTS.
      None expected.


      NOTES.

      1. NOAA 9 was permanently deactivated some years ago and is tumbling
      freely. Unfortunately it has a sporadic carrier on 137.500 (varies quickly
      according to orientation) and can cause interference to NOAA 12 and
      NOAA 15.

      2. NOAA 16's APT transmission system failed a few months after launch.

      3. Battery undervoltage safestate tripped causing power load shed which
      included AVHRR power off (and APT). Problem resolved and spacecraft now
      operating nominally. APT re-instated 30th July 15.25.


      LAUNCHES.

      The launch of Sich-1M is listed as 15th October 2004. I am
      indebted to Ian Deans for providing this information.

      NOAA N will launch on 11th February 2005.

      DIGITAL STATUS REPORT -- 2nd August 2004
      =================================

      CHANGES SINCE LAST REPORT.
      NOAA 12 HRPT back on.

      THIS WEEK'S EVENTS.
      None expected.

      Satellite Frequency Mode Remarks
      (MHz)
      NOAA 12 1698.0 HRPT Good signal.
      NOAA 14 1707.0 HRPT No data (see note 5)
      NOAA 15 1702.5 HRPT* Backup channel, weaker signal
      NOAA 16 1698.0 HRPT* Good signal (see note 7)
      NOAA 17 1707.0 HRPT* See note 6.
      FengYun 1C 1700.4 CHRPT Weak signal, use dish 90 cm.
      FengYun 1D 1700.4 CHRPT Good signal.
      Seastar 1702.5 SeaWifs signal OK
      encrypted


      NOTES.

      1. At the NOAA 17 frequency of 1707 MHz occasional interference may be
      expected from NOAA 14 at latitudes above 80 degrees. Erratic behaviour of
      the inactive NOAA 9 also has proven to be a source of interference at higher
      latitudes. NOAA 9 follows a similar track to 17. Recent reports suggest
      that this erratic behaviour is no longer being seen. My thanks to F. Valk
      for keeping us up to date with this problem.

      2. If you have a good LNA and analogue decoder (Timestep for example)
      all satellites with "Good signal" or better can already be received using
      a 1.5M helical beam (RIG Journal 64) or a small dish (60 to 80 cm) with
      helical feed.

      3. * These satellites have channel 3A/B which allows the composition of
      almost true-colour images of daylight passes using R3G2B1
      colour scheme. For more info on colouring see RIG Journal 69.

      4. ~ 10 Channel imager, use colour scheme R1G9B7 or R1G2B7 for
      daylight passes to get near true colour images.

      5. It is believed that during a test to switch off and then back on the
      NOAA 14 AVHRR scan mirror motor that the motor stalled.
      NOAA have confirmed that there are currently no plans to try and
      restart the stalled motor. There is no imagery available.

      6. Problems have developed with STX-3 (1707 MHZ). Power has dropped from
      approx. 8W to about 2.4W resulting on a greatly reduced signal strength.

      7. On Friday 19th September 2003 NOAA 16 developed AVHRR synch. problems
      similar to those on NOAA 14 (and previously NOAA 15).
      Since then reports have been mixed. Some periods of good data, some
      poor.

            None.

            THIS WEEK'S POSSIBLE EVENTS.
            None expected.


            NOTES.

            1. NOAA 9 was permanently deactivated some years ago and is tumbling
            freely. Unfortunately it has a sporadic carrier on 137.500 (varies quickly
            according to orientation) and can cause interference to NOAA 12 and
            NOAA 15.

            2. NOAA 16's APT transmission system failed a few months after launch.


            LAUNCHES.

            The launch of Sich-1M is listed as 15th October 2004. I am
            indebted to Ian Deans for providing this information.

            NOTES.

            1. At the NOAA 17 frequency of 1707 MHz occasional interference may be
            expected from NOAA 14 at latitudes above 80 degrees. Erratic behaviour of
            the inactive NOAA 9 also has proven to be a source of interference at higher
            latitudes. NOAA 9 follows a similar track to 17. Recent reports suggest
            that this erratic behaviour is no longer being seen. My thanks to F. Valk
            for keeping us up to date with this problem.

            2. If you have a good LNA and analogue decoder (Timestep for example)
            all satellites with "Good signal" or better can already be received using
            a 1.5M helical beam (RIG Journal 64) or a small dish (60 to 80 cm) with
            helical feed.

            3. * These satellites have channel 3A/B which allows the composition of
            almost true-colour images of daylight passes using R3G2B1
            colour scheme. For more info on colouring see RIG Journal 69.

            4. ~ 10 Channel imager, use colour scheme R1G9B7 or R1G2B7 for
            daylight passes to get near true colour images.

            5. It is believed that during a test to switch off and then back on the
            NOAA 14 AVHRR scan mirror motor that the motor stalled.
            NOAA have confirmed that there are currently no plans to try and
            restart the stalled motor. There is no imagery available.

            6. Problems have developed with STX-3 (1707 MHZ). Power has dropped from
            approx. 8W to about 2.4W resulting on a greatly reduced signal strength.

            7. On Friday 19th September 2003 NOAA 16 developed AVHRR synch. problems
            similar to those on NOAA 14 (and previously NOAA 15).
            Since then reports have been mixed. Some periods of good data, some
            poor.

            NOTES.

            1. If necessary the satellite may operate beyond this date.

            2. HRIT & LRIT data will not be disseminated through the satellite but will
            be provided via Hotbird satellite in DVB mode. See the Eumetcast status
            report for more information.

            3. Meteosat 5 now operates with only one channel.

            4. Meteosat 6 is the standby satellite for Meteosat 7. Whilst in standby is
            being used to provide a 10 minute rapid scan service of Europe on HRI.

            5. Insat 3A is a combined data and meteorological satellite.

            6. GMS-5 ceased VISSR transmissions on 22nd May 2003. Wefax is now
            derived from GOES-9 (155° E) GVAR and processed to a 140° aspect
            through GMS-5. For further information see :-
            http://www.jma.go.jp/JMA_HP/jma/indexe.html

            7. For those interested in EMWIN data, the following sats/frequencies apply.

            GOES 7 (175 W) 1690.725 MHz.
            GOES 10 (135 W) 1690.725 MHz
            GOES 12 (74.5 W) 1690.725 MHz
            For further info. there are many sources but the following is
            particularly informative:-
            http://iwin.nws.noaa.gov/emwin/user-intro.htm

            8. Currently Wefax alignment problems make animation difficult. It is hoped
            this problem will be resolved soon.

            9. LRIT is now operational in time share mode from GOES East. For further
            information go to : http://noaasis.noaa.gov/LRIT/
            Full LRIT on GOES East will commence Autumn 2004.

            10. MSG-1 became operational on 29th January 2004, and is now known as
            Meteosat 8.

              NOAA have confirmed that there are currently no plans to try and
              restart the stalled motor. There is no imagery available.

              6. Problems have developed with STX-3 (1707 MHZ). Power has dropped from
              approx. 8W to about 2.4W resulting on a greatly reduced signal strength.

              7. On Friday 19th September 2003 NOAA 16 developed AVHRR synch. problems
              similar to those on NOAA 14 (and previously NOAA 15).
              Since then reports have been mixed. Some periods of good data, some
              poor.

              NOTES.

              1. If necessary the satellite may operate beyond this date.

              2. HRIT & LRIT data will not be disseminated through the satellite but will
              be provided via Hotbird satellite in DVB mode. See the Eumetcast status
              report for more information.

              3. Meteosat 5 now operates with only one channel.

              4. Meteosat 6 is the standby satellite for Meteosat 7. Whilst in standby is
              being used to provide a 10 minute rapid scan service of Europe on HRI.

              5. Insat 3A is a combined data and meteorological satellite.

              6. GMS-5 ceased VISSR transmissions on 22nd May 2003. Wefax is now
              derived from GOES-9 (155° E) GVAR and processed to a 140° aspect
              through GMS-5. For further information see :-
              http://www.jma.go.jp/JMA_HP/jma/indexe.html

              7. For those interested in EMWIN data, the following sats/frequencies apply.

              GOES 7 (175 W) 1690.725 MHz.
              GOES 10 (135 W) 1690.725 MHz
              GOES 12 (74.5 W) 1690.725 MHz
              For further info. there are many sources but the following is
              particularly informative:-
              http://iwin.nws.noaa.gov/emwin/user-intro.htm

              8. Currently Wefax alignment problems make animation difficult. It is hoped
              this problem will be resolved soon.

              9. LRIT is now operational in time share mode from GOES East. For further
              information go to : http://noaasis.noaa.gov/LRIT/
              Full LRIT on GOES East will commence Autumn 2004.

              10. MSG-1 became operational on 29th January 2004, and is now known as
              Meteosat 8.

                Advanced warning of NOAA 12/15 conflict. See note 3.

                THIS WEEK'S POSSIBLE EVENTS.
                None expected.


                NOTES.

                1. NOAA 9 was permanently deactivated some years ago and is tumbling
                freely. Unfortunately it has a sporadic carrier on 137.500 (varies quickly
                according to orientation) and can cause interference to NOAA 12 and
                NOAA 15.

                2. NOAA 16's APT transmission system failed a few months after launch.

                3. There will be a NOAA 12/15 VHF (137.500) conflict commencing about 17th
                September 2004. Expect NOAA 15 to be switched off. Conflict lasts
                approximately 31 days.


                LAUNCHES.

                Whilst the launch of Sich-1M is still listed with some sites as 15th October
                2004, I am advised that a reliable Russian site now says NET November.
                This project has been about for at least 5 years so I suggest we don't hold
                our breath. Thanks to Ian Deans for providing this information.

                NOAA N launch NET 1st February 2005.
                NOAA N' launch.....TBA.

                ====================================

                CHANGES SINCE LAST REPORT.
                Update to Feng Yun 1C.

                THIS WEEK'S EVENTS.

                encrypted


                NOTES.

                1. At the NOAA 17 frequency of 1707 MHz occasional interference may be
                expected from NOAA 14 at latitudes above 80 degrees. Erratic behaviour of
                the inactive NOAA 9 also has proven to be a source of interference at higher
                latitudes. NOAA 9 follows a similar track to 17. Recent reports suggest
                that this erratic behaviour is no longer being seen. My thanks to F. Valk
                for keeping us up to date with this problem.

                2. If you have a good LNA and analogue decoder (Timestep for example)
                all satellites with "Good signal" or better can already be received using
                a 1.5M helical beam (RIG Journal 64) or a small dish (60 to 80 cm) with
                helical feed.

                3. * These satellites have channel 3A/B which allows the composition of
                almost true-colour images of daylight passes using R3G2B1
                colour scheme. For more info on colouring see RIG Journal 69.

                4. ~ 10 Channel imager, use colour scheme R1G9B7 or R1G2B7 for
                daylight passes to get near true colour images.

                5. It is believed that during a test to switch off and then back on the
                NOAA 14 AVHRR scan mirror motor that the motor stalled.
                NOAA have confirmed that there are currently no plans to try and
                restart the stalled motor. There is no imagery available.

                6. Problems have developed with STX-3 (1707 MHZ). Power has dropped from
                approx. 8W to about 2.4W resulting on a greatly reduced signal strength.

                7. On Friday 19th September 2003 NOAA 16 developed AVHRR synch. problems
                similar to those on NOAA 14 (and previously NOAA 15).
                Since then reports have been mixed. Some periods of good data, some
                poor.

                8. Although all channels are functioning on Feng Yun 1C, the image is
                not synchronised so the scan line is distorted.
                This results in having the edge of the earth, or at least the scan
                line, in the centre of the image.

                NOTES.

                1. If necessary the satellite may operate beyond this date.

                2. HRIT & LRIT data will not be disseminated through the satellite but will
                be provided via Hotbird satellite in DVB mode. See the Eumetcast status
                report for more information.

                3. Meteosat 5 now operates with only one channel.

                4. Meteosat 6 is the standby satellite for Meteosat 7. Whilst in standby is
                being used to provide a 10 minute rapid scan service of Europe on HRI.

                5. Insat 3A is a combined data and meteorological satellite.

                6. GMS-5 ceased VISSR transmissions on 22nd May 2003. Wefax is now
                derived from GOES-9 (155° E) GVAR and processed to a 140° aspect
                through GMS-5. For further information see :-
                http://www.jma.go.jp/JMA_HP/jma/indexe.html

                7. For those interested in EMWIN data, the following sats/frequencies apply.

                GOES 7 (175 W) 1690.725 MHz.
                GOES 10 (135 W) 1690.725 MHz
                GOES 12 (74.5 W) 1690.725 MHz
                For further info. there are many sources but the following is
                particularly informative:-
                http://iwin.nws.noaa.gov/emwin/user-intro.htm

                8. Currently Wefax alignment problems make animation difficult. It is hoped
                this problem will be resolved soon.

                9. LRIT is now operational in time share mode from GOES East. For further
                information go to : http://noaasis.noaa.gov/LRIT/
                Full LRIT on GOES East will commence Autumn 2004.

                10. MSG-1 became operational on 29th January 2004, and is now known as
                Meteosat 8.

                  None.

                  THIS WEEK'S POSSIBLE EVENTS.
                  NOAA 15's APT will be switched off 19th September. See note 3.

                  NOTES.

                  1. NOAA 9 was permanently deactivated some years ago and is tumbling
                  freely. Unfortunately it has a sporadic carrier on 137.500 (varies quickly
                  according to orientation) and can cause interference to NOAA 12 and
                  NOAA 15.

                  2. NOAA 16's APT transmission system failed a few months after launch.

                  3. There will be a NOAA 12/15 VHF (137.500) conflict commencing about 19th
                  September 2004. NOAA 15 will be switched off 19th September, 22.00 UTC. It
                  will remain off until 20th October, 18.00 UTC.


                  LAUNCHES.

                  The launch of Sich-1M will be NET November 2004.
                  This project has been about for at least 5 years so I suggest we don't hold
                  our breath. Thanks to Ian Deans for providing this information.

                  NOAA N launch NET 1st February 2005.
                  NOAA N' launch.....TBA.

                  DIGITAL STATUS REPORT -- 13th September 2004
                  =====================================

                  CHANGES SINCE LAST REPORT.
                  None.

                  THIS WEEK'S EVENTS.
                  None expected.

                  Satellite Frequency Mode Remarks
                  (MHz)
                  NOAA 12 1698.0 HRPT Good signal.
                  NOAA 14 1707.0 HRPT No data (see note 5)
                  NOAA 15 1702.5 HRPT* Backup channel, weaker signal
                  NOAA 16 1698.0 HRPT* Good signal (see note 7)
                  NOAA 17 1707.0 HRPT* See note 6.
                  Feng Yun 1C 1700.4 CHRPT See note 8.
                  Feng Yun 1D 1700.4 CHRPT Good signal.
                  Seastar 1702.5 SeaWifs signal OK
                  encrypted


                  NOTES.

                  1. At the NOAA 17 frequency of 1707 MHz occasional interference may be
                  expected from NOAA 14 at latitudes above 80 degrees. Erratic behaviour of
                  the inactive NOAA 9 also has proven to be a source of interference at higher
                  latitudes. NOAA 9 follows a similar track to 17. Recent reports suggest
                  that this erratic behaviour is no longer being seen. My thanks to F. Valk
                  for keeping us up to date with this problem.

                  2. If you have a good LNA and analogue decoder (Timestep for example)
                  all satellites with "Good signal" or better can already be received using
                  a 1.5M helical beam (RIG Journal 64) or a small dish (60 to 80 cm) with
                  helical feed.

                  3. * These satellites have channel 3A/B which allows the composition of
                  almost true-colour images of daylight passes using R3G2B1
                  colour scheme. For more info on colouring see RIG Journal 69.

                  4. ~ 10 Channel imager, use colour scheme R1G9B7 or R1G2B7 for
                  daylight passes to get near true colour images.

                  5. It is believed that during a test to switch off and then back on the
                  NOAA 14 AVHRR scan mirror motor that the motor stalled.
                  NOAA have confirmed that there are currently no plans to try and
                  restart the stalled motor. There is no imagery available.

                  6. Problems have developed with STX-3 (1707 MHZ). Power has dropped from
                  approx. 8W to about 2.4W resulting on a greatly reduced signal strength.

                  7. On Friday 19th September 2003 NOAA 16 developed AVHRR synch. problems
                  similar to those on NOAA 14 (and previously NOAA 15).
                  Since then reports have been mixed. Some periods of good data, some
                  poor.

                  8. Although all channels are functioning on Feng Yun 1C, the image is
                  not synchronised so the scan line is distorted.
                  This results in having the edge of the earth, or at least the scan
                  line, in the centre of the image.

                  NOTES.

                  1. If necessary the satellite may operate beyond this date.

                  2. HRIT & LRIT data will not be disseminated through the satellite but will
                  be provided via Hotbird satellite in DVB mode. See the Eumetcast status
                  report for more information.

                  3. Meteosat 5 now operates with only one channel.

                  4. Meteosat 6 is the standby satellite for Meteosat 7. Whilst in standby is
                  being used to provide a 10 minute rapid scan service of Europe on HRI.

                  5. Insat 3A is a combined data and meteorological satellite.

                  6. GMS-5 ceased VISSR transmissions on 22nd May 2003. Wefax is now
                  derived from GOES-9 (155° E) GVAR and processed to a 140° aspect
                  through GMS-5. For further information see :-
                  http://www.jma.go.jp/JMA_HP/jma/indexe.html

                  7. For those interested in EMWIN data, the following sats/frequencies apply.

                  GOES 7 (175 W) 1690.725 MHz.
                  GOES 10 (135 W) 1690.725 MHz
                  GOES 12 (74.5 W) 1690.725 MHz
                  For further info. there are many sources but the following is
                  particularly informative:-
                  http://iwin.nws.noaa.gov/emwin/user-intro.htm

                  8. Currently Wefax alignment problems make animation difficult. It is hoped
                  this problem will be resolved soon.

                  9. LRIT is now operational in time share mode from GOES East. For further
                  information go to : http://noaasis.noaa.gov/LRIT/
                  Full LRIT on GOES East will commence Autumn 2004.

                  10. MSG-1 became operational on 29th January 2004, and is now known as
                  Meteosat 8.

                    NOAA 15 off.

                    THIS WEEK'S POSSIBLE EVENTS.
                    None expected.

                    NOTES.

                    1. NOAA 9 was permanently deactivated some years ago and is tumbling
                    freely. Unfortunately it has a sporadic carrier on 137.500 (varies quickly
                    according to orientation) and can cause interference to NOAA 12 and
                    NOAA 15.

                    2. NOAA 16's APT transmission system failed a few months after launch.

                    3. Due to a NOAA 12/15 VHF (137.500) conflict, NOAA 15 will be switched off
                    from 19th September, 22.00 UTC until 20th October, 18.00 UTC.


                    LAUNCHES.

                    The launch of Sich-1M will be NET November 2004.
                    This project has been about for at least 5 years so I suggest we don't hold
                    our breath. Thanks to Ian Deans for providing this information.

                    NOAA N launch NET 1st February 2005.
                    NOAA N' launch.....TBA.

                    CHANGES SINCE LAST REPORT.
                    None.

                    THIS WEEK'S EVENTS.
                    None expected.

                    NOTES.

                    1. At the NOAA 17 frequency of 1707 MHz occasional interference may be
                    expected from NOAA 14 at latitudes above 80 degrees. Erratic behaviour of
                    the inactive NOAA 9 also has proven to be a source of interference at higher
                    latitudes. NOAA 9 follows a similar track to 17. Recent reports suggest
                    that this erratic behaviour is no longer being seen. My thanks to F. Valk
                    for keeping us up to date with this problem.

                    2. If you have a good LNA and analogue decoder (Timestep for example)
                    all satellites with "Good signal" or better can already be received using
                    a 1.5M helical beam (RIG Journal 64) or a small dish (60 to 80 cm) with
                    helical feed.

                    3. * These satellites have channel 3A/B which allows the composition of
                    almost true-colour images of daylight passes using R3G2B1
                    colour scheme. For more info on colouring see RIG Journal 69.

                    4. ~ 10 Channel imager, use colour scheme R1G9B7 or R1G2B7 for
                    daylight passes to get near true colour images.

                    5. It is believed that during a test to switch off and then back on the
                    NOAA 14 AVHRR scan mirror motor that the motor stalled.
                    NOAA have confirmed that there are currently no plans to try and
                    restart the stalled motor. There is no imagery available.

                    6. Problems have developed with STX-3 (1707 MHZ). Power has dropped from
                    approx. 8W to about 2.4W resulting on a greatly reduced signal strength.

                    7. On Friday 19th September 2003 NOAA 16 developed AVHRR synch. problems
                    similar to those on NOAA 14 (and previously NOAA 15).
                    Since then reports have been mixed. Some periods of good data, some
                    poor.

                    8. Although all channels are functioning on Feng Yun 1C, the image is
                    not synchronised so the scan line is distorted.
                    This results in having the edge of the earth, or at least the scan
                    line, in the centre of the image.

                    NOTES.

                    1. If necessary the satellite may operate beyond this date.

                    2. HRIT & LRIT data will not be disseminated through the satellite but will
                    be provided via Hotbird satellite in DVB mode. See the Eumetcast status
                    report for more information.

                    3. Meteosat 5 now operates with only one channel.

                    4. Meteosat 6 is the standby satellite for Meteosat 7. Whilst in standby is
                    being used to provide a 10 minute rapid scan service of Europe on HRI.

                    5. Insat 3A is a combined data and meteorological satellite.

                    6. GMS-5 ceased VISSR transmissions on 22nd May 2003. Wefax is now
                    derived from GOES-9 (155° E) GVAR and processed to a 140° aspect
                    through GMS-5. For further information see :-
                    http://www.jma.go.jp/JMA_HP/jma/indexe.html

                    7. For those interested in EMWIN data, the following sats/frequencies apply.

                    GOES 7 (175 W) 1690.725 MHz.
                    GOES 10 (135 W) 1690.725 MHz
                    GOES 12 (74.5 W) 1690.725 MHz
                    For further info. there are many sources but the following is
                    particularly informative:-
                    http://iwin.nws.noaa.gov/emwin/user-intro.htm

                    8. Currently Wefax alignment problems make animation difficult. It is hoped
                    this problem will be resolved soon.

                    9. LRIT is now operational in time share mode from GOES East. For further
                    information go to : http://noaasis.noaa.gov/LRIT/
                    Full LRIT on GOES East will commence Autumn 2004.

                    10. MSG-1 became operational on 29th January 2004, and is now known as
                    Meteosat 8.

                      CHANGES SINCE LAST REPORT.
                      NOAA N launch put back.

                      THIS WEEK'S POSSIBLE EVENTS.
                      None expected.

                      NOTES.

                      1. NOAA 9 was permanently deactivated some years ago and is tumbling
                      freely. Unfortunately it has a sporadic carrier on 137.500 (varies quickly
                      according to orientation) and can cause interference to NOAA 12 and
                      NOAA 15.

                      2. NOAA 16's APT transmission system failed a few months after launch.

                      3. Due to a NOAA 12/15 VHF (137.500) conflict, NOAA 15 will be switched off
                      from 19th September, 22.00 UTC until 20th October, 18.00 UTC.


                      LAUNCHES.

                      The launch of Sich-1M will be NET November 2004.
                      This project has been about for at least 5 years so I suggest we don't hold
                      our breath. Thanks to Ian Deans for providing this information.

                      NOAA N launch NET 12th February 2005.
                      NOAA N' launch.....TBA.

                      NOTES.

                      1. At the NOAA 17 frequency of 1707 MHz occasional interference may be
                      expected from NOAA 14 at latitudes above 80 degrees. Erratic behaviour of
                      the inactive NOAA 9 also has proven to be a source of interference at higher
                      latitudes. NOAA 9 follows a similar track to 17. Recent reports suggest
                      that this erratic behaviour is no longer being seen. My thanks to F. Valk
                      for keeping us up to date with this problem.

                      2. If you have a good LNA and analogue decoder (Timestep for example)
                      all satellites with "Good signal" or better can already be received using
                      a 1.5M helical beam (RIG Journal 64) or a small dish (60 to 80 cm) with
                      helical feed.

                      3. * These satellites have channel 3A/B which allows the composition of
                      almost true-colour images of daylight passes using R3G2B1
                      colour scheme. For more info on colouring see RIG Journal 69.

                      4. ~ 10 Channel imager, use colour scheme R1G9B7 or R1G2B7 for
                      daylight passes to get near true colour images.

                      5. It is believed that during a test to switch off and then back on the
                      NOAA 14 AVHRR scan mirror motor that the motor stalled.
                      NOAA have confirmed that there are currently no plans to try and
                      restart the stalled motor. There is no imagery available.

                      6. Problems have developed with STX-3 (1707 MHZ). Power has dropped from
                      approx. 8W to about 2.4W resulting on a greatly reduced signal strength.

                      7. On Friday 19th September 2003 NOAA 16 developed AVHRR synch. problems
                      similar to those on NOAA 14 (and previously NOAA 15).
                      Since then reports have been mixed. Some periods of good data, some
                      poor.

                      8. Although all channels are functioning on Feng Yun 1C, the image is
                      not synchronised so the scan line is distorted.
                      This results in having the edge of the earth, or at least the scan
                      line, in the centre of the image.

                      NOTES.

                      1. If necessary the satellite may operate beyond this date.

                      2. HRIT & LRIT data will not be disseminated through the satellite but will
                      be provided via Hotbird satellite in DVB mode. See the Eumetcast status
                      report for more information.

                      3. Meteosat 5 now operates with only one channel.

                      4. Meteosat 6 is the standby satellite for Meteosat 7. Whilst in standby is
                      being used to provide a 10 minute rapid scan service of Europe on HRI.

                      5. Insat 3A is a combined data and meteorological satellite.

                      6. GMS-5 ceased VISSR transmissions on 22nd May 2003. Wefax is now
                      derived from GOES-9 (155° E) GVAR and processed to a 140° aspect
                      through GMS-5. For further information see :-
                      http://www.jma.go.jp/JMA_HP/jma/indexe.html

                      7. For those interested in EMWIN data, the following sats/frequencies apply.

                      GOES 7 (175 W) 1690.725 MHz.
                      GOES 10 (135 W) 1690.725 MHz
                      GOES 12 (74.5 W) 1690.725 MHz
                      For further info. there are many sources but the following is
                      particularly informative:-
                      http://iwin.nws.noaa.gov/emwin/user-intro.htm

                      8. Currently Wefax alignment problems make animation difficult. It is hoped
                      this problem will be resolved soon.

                      9. LRIT is now operational in time share mode from GOES East. For further
                      information go to : http://noaasis.noaa.gov/LRIT/
                      Full LRIT on GOES East will commence Autumn 2004.

                      10. MSG-1 became operational on 29th January 2004, and is now known as
                      Meteosat 8.

                        THIS WEEK'S POSSIBLE EVENTS.
                        None expected.

                        NOTES.

                        1. NOAA 9 was permanently deactivated some years ago and is tumbling
                        freely. Unfortunately it has a sporadic carrier on 137.500 (varies quickly
                        according to orientation) and can cause interference to NOAA 12 and
                        NOAA 15.

                        2. NOAA 16's APT transmission system failed a few months after launch.

                        3. Due to a NOAA 12/15 VHF (137.500) conflict, NOAA 15 will be switched off
                        from 19th September, 22.00 UTC until 20th October, 18.00 UTC.


                        LAUNCHES.

                        The launch of Sich-1M will be NET November 2004.
                        This project has been about for at least 5 years so I suggest we don't hold
                        our breath. Thanks to Ian Deans for providing this information.

                        NOTES.

                        1. At the NOAA 17 frequency of 1707 MHz occasional interference may be
                        expected from NOAA 14 at latitudes above 80 degrees. Erratic behaviour of
                        the inactive NOAA 9 also has proven to be a source of interference at higher
                        latitudes. NOAA 9 follows a similar track to 17. Recent reports suggest
                        that this erratic behaviour is no longer being seen. My thanks to F. Valk
                        for keeping us up to date with this problem.

                        2. If you have a good LNA and analogue decoder (Timestep for example)
                        all satellites with "Good signal" or better can already be received using
                        a 1.5M helical beam (RIG Journal 64) or a small dish (60 to 80 cm) with
                        helical feed.

                        3. * These satellites have channel 3A/B which allows the composition of
                        almost true-colour images of daylight passes using R3G2B1
                        colour scheme. For more info on colouring see RIG Journal 69.

                        4. ~ 10 Channel imager, use colour scheme R1G9B7 or R1G2B7 for
                        daylight passes to get near true colour images.

                        5. It is believed that during a test to switch off and then back on the
                        NOAA 14 AVHRR scan mirror motor that the motor stalled.
                        NOAA have confirmed that there are currently no plans to try and
                        restart the stalled motor. There is no imagery available.

                        6. Problems have developed with STX-3 (1707 MHZ). Power has dropped from
                        approx. 8W to about 2.4W resulting on a greatly reduced signal strength.

                        7. On Friday 19th September 2003 NOAA 16 developed AVHRR synch. problems
                        similar to those on NOAA 14 (and previously NOAA 15).
                        Since then reports have been mixed. Some periods of good data, some
                        poor.

                        8. Although all channels are functioning on Feng Yun 1C, the image is
                        not synchronised so the scan line is distorted.
                        This results in having the edge of the earth, or at least the scan
                        line, in the centre of the image.

                        NOTES.

                        1. If necessary the satellite may operate beyond this date.

                        2. HRIT & LRIT data will not be disseminated through the satellite but will
                        be provided via Hotbird satellite in DVB mode. See the Eumetcast status
                        report for more information.

                        3. Meteosat 5 now operates with only one channel.

                        4. Meteosat 6 is the standby satellite for Meteosat 7. Whilst in standby is
                        being used to provide a 10 minute rapid scan service of Europe on HRI.

                        5. Insat 3A is a combined data and meteorological satellite.

                        6. GMS-5 ceased VISSR transmissions on 22nd May 2003. Wefax is now
                        derived from GOES-9 (155° E) GVAR and processed to a 140° aspect
                        through GMS-5. For further information see :-
                        http://www.jma.go.jp/JMA_HP/jma/indexe.html

                        7. For those interested in EMWIN data, the following sats/frequencies apply.

                        GOES 7 (175 W) 1690.725 MHz.
                        GOES 10 (135 W) 1690.725 MHz
                        GOES 12 (74.5 W) 1690.725 MHz
                        For further info. there are many sources but the following is
                        particularly informative:-

                        8. Currently Wefax alignment problems make animation difficult. It is hoped
                        this problem will be resolved soon.

                        9. LRIT is now operational in time share mode from GOES East. For further
                        information go to : http://noaasis.noaa.gov/LRIT/
                        Full LRIT on GOES East will commence Autumn 2004.

                        10. MSG-1 became operational on 29th January 2004, and is now known as
                        Meteosat 8.

                          THIS WEEK'S POSSIBLE EVENTS.
                          None expected.

                          NOTES.

                          1. NOAA 9 was permanently deactivated some years ago and is tumbling
                          freely. Unfortunately it has a sporadic carrier on 137.500 (varies quickly
                          according to orientation) and can cause interference to NOAA 12 and
                          NOAA 15.

                          2. NOAA 16's APT transmission system failed a few months after launch.

                          3. Due to a NOAA 12/15 VHF (137.500) conflict, NOAA 15 will be switched off
                          from 19th September, 22.00 UTC until 20th October, 18.00 UTC.


                          LAUNCHES.

                          The launch of Sich-1M will be NET November 2004.
                          This project has been about for at least 5 years so I suggest we don't hold
                          our breath. Thanks to Ian Deans for providing this information.

                          NOAA N launch NET 12th February 2005.

                          NOTES.

                          1. At the NOAA 17 frequency of 1707 MHz occasional interference may be
                          expected from NOAA 14 at latitudes above 80 degrees. Erratic behaviour of
                          the inactive NOAA 9 also has proven to be a source of interference at higher
                          latitudes. NOAA 9 follows a similar track to 17. Recent reports suggest
                          that this erratic behaviour is no longer being seen. My thanks to F. Valk
                          for keeping us up to date with this problem.

                          2. If you have a good LNA and analogue decoder (Timestep for example)
                          all satellites with "Good signal" or better can already be received using
                          a 1.5M helical beam (RIG Journal 64) or a small dish (60 to 80 cm) with
                          helical feed.

                          3. * These satellites have channel 3A/B which allows the composition of
                          almost true-colour images of daylight passes using R3G2B1
                          colour scheme. For more info on colouring see RIG Journal 69.

                          4. ~ 10 Channel imager, use colour scheme R1G9B7 or R1G2B7 for
                          daylight passes to get near true colour images.

                          5. It is believed that during a test to switch off and then back on the
                          NOAA 14 AVHRR scan mirror motor that the motor stalled.
                          NOAA have confirmed that there are currently no plans to try and
                          restart the stalled motor. There is no imagery available.

                          6. Problems have developed with STX-3 (1707 MHZ). Power has dropped from
                          approx. 8W to about 2.4W resulting on a greatly reduced signal strength.

                          7. On Friday 19th September 2003 NOAA 16 developed AVHRR synch. problems
                          similar to those on NOAA 14 (and previously NOAA 15).
                          Since then reports have been mixed. Some periods of good data, some
                          poor.

                          8. Although all channels are functioning on Feng Yun 1C, the image is
                          not synchronised so the scan line is distorted.
                          This results in having the edge of the earth, or at least the scan
                          line, in the centre of the image.

                          NOTES.

                          1. If necessary the satellite may operate beyond this date.

                          2. HRIT & LRIT data will not be disseminated through the satellite but will
                          be provided via Hotbird satellite in DVB mode. See the Eumetcast status
                          report for more information.

                          3. Meteosat 5 now operates with only one channel.

                          4. Meteosat 6 is the standby satellite for Meteosat 7. Whilst in standby is
                          being used to provide a 10 minute rapid scan service of Europe on HRI.

                          5. Insat 3A is a combined data and meteorological satellite.

                          6. GMS-5 ceased VISSR transmissions on 22nd May 2003. Wefax is now
                          derived from GOES-9 (155° E) GVAR and processed to a 140° aspect
                          through GMS-5. For further information see :-
                          http://www.jma.go.jp/JMA_HP/jma/indexe.html

                          7. For those interested in EMWIN data, the following sats/frequencies apply.

                          GOES 7 (175 W) 1690.725 MHz.
                          GOES 10 (135 W) 1690.725 MHz
                          GOES 12 (74.5 W) 1690.725 MHz
                          For further info. there are many sources but the following is
                          particularly informative:-
                          http://iwin.nws.noaa.gov/emwin/user-intro.htm

                          8. Currently Wefax alignment problems make animation difficult. It is hoped
                          this problem will be resolved soon.

                          9. LRIT is now operational in time share mode from GOES East. For further
                          information go to : http://noaasis.noaa.gov/LRIT/
                          Full LRIT on GOES East will commence Autumn 2004.

                          10. MSG-1 became operational on 29th January 2004, and is now known as
                          Meteosat 8.
