      ** Aurora Watch In Effect **

      The Earth is now inside of a coronal hole high speed solar wind
      stream, and G-1 geomagnetic storm conditions have been observed within
      the last 24 hours. Therefore, an aurora watch is in effect.
      Skywatchers in the higher latitudes should keep an eye to the sky for
      aurora. Other than that, there isn't much happening as solar activity
      remains low. There are three small numbered sunspot regions visible,
      but none appear to have any significant flare generating capability at
      the present time.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 49
      SFI : 94
      A index : 10
      K index : 2

      Solar wind speed : 627.9 km/sec
      Solar wind density : 2.1 protons/cc
      Solar wind pressure : 1.6 nPa

      IMF : 6.8 nT
      IMF Orientation : 1.6 nT North

      Conditions for the last 24 hours :
      Space weather for the past 24 hours has been minor. Geomagnetic storms
      reaching the G1 level occurred.

      Forecast for the next 24 hours :
      No space weather storms are expected for the next 24 hours.

      Solar activity forecast :
      Solar activity is expected to be low. Additional small flares are
      expected in Region 549. There is a chance of a small M-class flare in
      this region as well.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be mostly unsettled to active
      with the possibility of isolated minor storm periods as the coronal
      hole induced disturbance continues.

      Recent significant solar flare activity :
      None
