Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 304 Issued at 2200Z on 31 Oct 2006
IA.  Analysis of Solar Active Regions and Activity from  30/2100Z
to 31/2100Z:  Solar activity was very low. Region 921 (S07E44) has
increased in area to approximately 120 millionths and is now
classified as a beta gamma magnetic group. New Region 922 (S15E58)
was numbered today. At 31/0518 UTC, LASCO C3 imagery showed a halo
CME with an approximate plane of sky speed at 390 km/s. This CME is
likely a backsided event and therefore, not geoeffective.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low to low. Isolated C-flare activity is possible from Region 921.
IIA.  Geophysical Activity Summary 30/2100Z to 31/2100Z:
The geomagnetic field was quiet. The greater than 2 MeV electron flux
at geosynchronous orbit reached high levels today.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled.
