Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 090 Issued at 2200Z on 31 Mar 2005
IA.  Analysis of Solar Active Regions and Activity from  30/2100Z
to 31/2100Z:  Solar activity remains at very low levels.  Regions 747
(S07E23) and 748 (N09E59) are both HSX alpha spot groups that were
numbered today.  Region 745 (N11W80) continues a slow decay and is
now spotless.
IB.  Solar Activity Forecast:  Solar activity is expected to continue
at very low levels.
IIA.  Geophysical Activity Summary 30/2100Z to 31/2100Z:
The geomagnetic field was at quiet to unsettled levels.  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 at quiet to unsettled levels through 1 April. 
Isolated minor storming conditions are expected late on 2 April due
to the onset of a recurrent coronal hole high speed stream and
should continue through 3 April.
