      The flares have been coming hot and heavy over the last several days,
      finishing up with an M1.8 flare on the 6th. The fun may be over for a
      time, however, since sunspot region 17 has rotated out of view.
      Sunspot region 19, however, has a chance of generating at least a
      modest M-class flare. The Earth is inside of a coronal hole generated
      high speed solar wind stream this evening, which is expected to
      persist. On the heels of the coronal hole that is affecting the solar
      wind speeds now is a smaller one that should be coming into an
      Earth-pointing position in a couple of days. We may see some more
      solar wind gusts from it late in the week. Although geomagnetic
      activity is relatively quiet for the time being, some aurora displays
      aren't out of the question for the higher latitudes.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 123
      SFI : 134
      A index : 21
      K index : 3

      Solar wind speed : 447.5 km/sec
      Solar wind density : 2.0 protons/cc
      Solar wind pressure : 0.6 nPa

      IMF : 4.2 nT
      IMF Orientation : 0.8 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 low to moderate. Region 19 remains
      capable of C-class activity. An isolated M-class flare in this region
      is also possible.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be unsettled to active as the
      coronal hole disturbance continues.

      Recent significant solar flare activity :
      06-Jul-2002 0342Z M1.8
      05-Jul-2002 1326Z M3.2
      04-Jul-2002 0734Z M1.1
