Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 093 Issued at 2200Z on 03 Apr 2010
IA.  Analysis of Solar Active Regions and Activity from  02/2100Z
to 03/2100Z:  Solar activity was very low. Region 1059 (S22W15)
produced a long-duration B7 x-ray event at 0954Z which was
associated with a halo CME. The CME plane-of-sky speed was estimated
to be about 500 km/s. Regions 1059 and 1057 (N16W72) were generally
unchanged during the past 24 hours.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low for the next three days (4-6 April). There is however, a slight
chance for an isolated C-class event.
IIA.  Geophysical Activity Summary 02/2100Z to 03/2100Z:
The geomagnetic field was quiet to unsettled during the past 24
hours.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet for the next two days (4-5 April). An increase
to quiet to unsettled with a chance for an active period is expected
late on the third day (6 April) due to possible effects from a
favorably positioned coronal hole.
