Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 089 Issued at 2200Z on 30 Mar 2006
IA.  Analysis of Solar Active Regions and Activity from  29/2100Z
to 30/2100Z:  Solar activity was very low. Today's activity consisted
of several B-class flares. Most of these were from Region 865
(S13E32) including the largest, a B9/Sf at 1517Z. Region 865 is
showing slow growth and is currently a 140 millionths D-type sunspot
group. Region 866 (S08E56) managed to produce a B7 flare at 1709 UTC
but was otherwise quiet and stable.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low to low. There is a fair chance for an isolated C-class event from
Region 865 sometime during the next three days (31 Mar - 2 Apr).
IIA.  Geophysical Activity Summary 29/2100Z to 30/2100Z:
The geomagnetic field was quiet during the past 24 hours.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet for the next two days (31 Mar - 1 Apr) and is
expected to be generally unsettled by the third day (2 Apr).
