      ** Aurora Watch In Effect **

      A few days earlier than had been expected, the Earth has entered the
      high speed solar wind stream from the coronal hole mentioned in the
      last report. The solar wind speed and density are both elevated, and
      high latitude skywatchers should keep an eye out for aurora. There
      have been two M-class flares today, including a nice M3-class flare.
      The sunspot number is also a bit higher than it has been of late. Both
      of these things are thanks to sunspot region 9885, a new, rapidly
      growing sunspot group. This sunspot region definitely has the
      potential for producing more flares in the days ahead.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 171
      SFI : 189
      A index : 18
      K index : 2

      Solar wind speed : 661.1 km/sec
      Solar wind density : 3.6 protons/cc
      Solar wind pressure : 2.4 nPa

      IMF : 12.0 nT
      IMF Orientation : 1.9 nT North

      Conditions for the last 24 hours :
      Space weather for the past 24 hours has been minor. Radio blackouts
      reaching the R1 level occurred.

      Forecast for the next 24 hours :
      Space weather for the next 24 hours is expected to be minor. Radio
      blackouts reaching the R1 level are expected.

      Solar activity forecast :
      Solar activity is expected to be moderate. Region 9885 is expected to
      produce additional M-class activity and may generate an isolated
      X-flare.

      Forecast for the next 24 hours :
      The geomagnetic field is expected to range from quiet to active levels
      for the duration of the 3-day forecast period.

      Recent significant solar flare activity :
      30-Mar-2002 2226Z M1.0
      30-Mar-2002 1301Z M3.4
