      The continued low level of activity is becoming a bit of a story in
      itself. The sunspot number is quite low, and is similar to something
      you would expect to see close to the solar minimum instead of the
      solar maximum. Only a mildly elevated solar wind speed and density is
      serving to break the doldrums. At present, there are 4 numbered
      sunspot groups visible. Of those, 9991 could conceivable generate a
      low-level M-class flare. When 9987 finishes rotating out of view,
      there will only be 3 sunspot groups, and the sunspot number could drop
      even lower.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 102
      SFI : 131
      A index : 5
      K index : 2

      Solar wind speed : 350.8 km/sec
      Solar wind density : 5.4 protons/cc
      Solar wind pressure : 1.0 nPa

      IMF : 3.4 nT
      IMF Orientation : 0.8 nT North

      Conditions for the last 24 hours :
      No space weather storms were observed for the past 24 hours.

      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. Region 9987 and 9991 have the
      potential of C- and low level M-class events. Old Region 9963 (N17, L=
      318) is due to return on day two of the forecast period.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be a quiet to unsettled levels.
      Isolated active conditions are possible on day one of the forecast
      period due to coronal hole effects.

      Recent significant solar flare activity :
      None
