Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 087 Issued at 2200Z on 28 Mar 2010
IA.  Analysis of Solar Active Regions and Activity from  27/2100Z
to 28/2100Z:  Solar activity was very low. Region 1057 (N15E04)
remained at a Beta magnetic classification while growing in size.
Region 1059 (S22E61), now a Hax Alpha spot has increased in size as
well.
IB.  Solar Activity Forecast:  Solar activity is expected to be low
with C-class flares expected and a slight chance for a M-class flare
over the next 3 days (29-31 March).
IIA.  Geophysical Activity Summary 27/2100Z to 28/2100Z:
The geomagnetic field was quiet with an isolated period of unsettled
to active conditions between 03-06Z.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to remain mostly quiet for day 1 (29 March), with brief
periods of unsettled to active conditions possible days 2-3 (30-31
March) due to brief periods of Bz south with slightly elevated solar
wind speeds.
