Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 093 Issued at 2200Z on 02 Apr 2008
IA.  Analysis of Solar Active Regions and Activity from  01/2100Z
to 02/2100Z:  Solar activity was very low. No significant flare
activity occurred. Region 987 (S08W89) was quiet and stable as it
neared the west limb. Region 988 (S07W63) remained a stable H-type.
Minor filament activity was reported in plage Region 989 (S11W28).
No new regions were numbered.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 01/2100Z to 02/2100Z:
The geomagnetic field was quiet. The greater than 2 MeV electron flux
at geosynchronous orbit was high.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet on day 1 (03 April). Activity is expected to
increase to unsettled levels on day 2 (04 April) with active periods
at high latitudes as a recurrent coronal hole high-speed stream
becomes geoeffective. A further increase to active levels is
expected on day 3 (05 April) with minor to major storm periods at
high latitudes as the high-speed stream continues.
