      ** G-1 Geomagnetic Storm In Progress **
      ** Aurora Watch In Effect **

      The Earth has entered a high speed coronal hole solar wind stream, and
      geomagnetic storm conditions have reached the G-3 (strong) level
      within the last 24 hours. The current solar wind speed has surpassed
      the 700 km/sec mark. The geomagnetic storm activity has subsided a
      bit, but a G-1 geomagnetic storm is still in progress. The current
      active conditions are expected to last for the next 72 hours as the
      high speed solar wind continues. Don't be surprised to see more
      geomagnetic storms through the period. There isn't much in the way of
      sunspot or flare activity to report. There are only two numbered
      sunspot regions visible tonight, and neither look to have the
      potential to generate any significant flares for the time being.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 62
      SFI : 119
      A index : 51
      K index : 5

      Solar wind speed : 732.2 km/sec
      Solar wind density : 1.4 protons/cc
      Solar wind pressure : 1.0 nPa

      IMF : 9.9 nT
      IMF Orientation : 2.0 nT South

      Conditions for the last 24 hours :
      Space weather for the past 24 hours has been strong. Geomagnetic
      storms reaching the G3 level occurred.

      Forecast for the next 24 hours :
      Space weather for the next 24 hours is expected to be minor.
      Geomagnetic storms reaching the G1 level are expected.

      Solar activity forecast :
      Solar activity is expected to be low. C-class flares are possible in
      Regions 431, 436, and an area not yet numbered rotating around the
      east limb near S12E90.

      Geomagnetic activity forecast :
      The geomagnetic field is
      expected to be at mostly active to minor storm levels for the
      duration of the forecast period as the high-speed-stream disturbance
      continues.

      Recent significant solar flare activity :
      None
