Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 092 Issued at 2200Z on 01 Apr 2008
IA.  Analysis of Solar Active Regions and Activity from  31/2100Z
to 01/2100Z:  Solar activity was very low. Today's activity consisted
to two, low-level B-class flares, both from Region 989 (S11W14).
Region 989 has decayed to spotless plage and Regions 987 (S08W75)
and 988 (S07W50) were both in decline.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low. There is, however, a slight chance for an isolated C-class
flare during the next three days.
IIA.  Geophysical Activity Summary 31/2100Z to 01/2100Z:
The geomagnetic field was mostly quiet during the past 24 hours. The
greater than 2 MeV electron flux at geosynchronous orbit reached
high levels during the past 24 hours.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be generally quiet for the next three days (02-04
April).
