Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 091 Issued at 2200Z on 01 Apr 2006
IA.  Analysis of Solar Active Regions and Activity from  31/2100Z
to 01/2100Z:  Solar activity was very low. Today's activity consisted
of a few B-class flares. The largest of these was a B7 at 0040Z from
Region 865 (S12E07). This region continues to grow slowly,
particularly in the intermediate spots, and it does show some
magnetic complexity.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low to low. There is a chance for an isolated C-class event from
Region 865 during the next three days (02-04 April).
IIA.  Geophysical Activity Summary 31/2100Z to 01/2100Z:
The geomagnetic field was quiet.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled for the next three days (02-04
April)
