      All is quiet now as sunspot region 652 has rotated out of view. It
      did not leave quietly, however. A massive prominence was seen to
      erupt on the western limb of the solar disk, and I suspect it was in
      conjunction with a long duration C8-class flare. There was a big CME
      accompanying the event. While it wasn't Earth-directed, it sure
      looked impressive in the SOHO coronagraph imagery. For the next few
      days, expect things to remain quiet. There are two small sunspot
      regions visible, but neither appear to have flare-generating potential
      at the present time.

      The current solar and geopmagnetic conditions are :

      NOAA sunspot number : 40
      SFI : 83
      A index : 11
      K index : 3

      Solar wind speed : 446.5 km/sec
      Solar wind density : 1.3 protons/cc
      Solar wind pressure : 0.5 nPa

      IMF : 4.5 nT
      IMF Orientation : 4.0 nT North

      GOES-12 Background X-ray Flux level : A9

      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 at very low to low levels. Region 655
      has the potential to produce isolated C-class flares.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be at quiet to unsettled levels
      throughout the forecast period.

      Recent significant solar flare activity :
      None
