SDF Number 039 Issued at 2200Z on 08 Feb 2010
IA.  Analysis of Solar Active Regions and Activity from  07/2100Z
to 08/2100Z:  Solar activity was moderate.  Region 1045 (N23W17)
produced three M-class events in the last 24 hours.  STEREO and
SOHO/LASCO imagery observed CME activity with each of the three
events.  The largest event was a M4 at 08/0743Z with an associated
Tenflare of 150 sfu.  This region has continued to grow in both
white light area coverage and sunspot count and is a magnetic
beta-gamma-delta configuration.  There were two additional Tenflares
observed during the period (both associated with Region 1045
events), a C7/Sf at 08/0415Z with a 100 sfu Tenflare, and a C8/1f at
08/0523Z with a 100 sfu Tenflare.  A new region was numbered today
as Region 1047 (S15E70).
IB.  Solar Activity Forecast:  Solar activity is expected to be
moderate with M-class flares likely.  There is a slight chance for a
X-class event from Region 1045.
IIA.  Geophysical Activity Summary 07/2100Z to 08/2100Z:
The geomagnetic field was quiet.  One unsettled period at
mid-latitudes was reported at 08/1600Z.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be predominantly unsettled with isolated active
conditions for the next three days (09-11 February).  These
conditions are forecast due to the recent CME activity.
