Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 091 Issued at 2200Z on 31 Mar 2008
IA.  Analysis of Solar Active Regions and Activity from  30/2100Z
to 31/2100Z:  Solar activity was very low. Region 988 (S07W35)
produced today's only B-class flare, a B2/Sf at 0534Z. All three
regions on the disk were quiet and stable and show an overall
declining trend.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 30/2100Z to 31/2100Z:
The geomagnetic field was quiet. The greater than 2 MeV electron flux
at geosynchronous orbit was high during the past 24 hours.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet for the next three days (01-03 April).
