Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 360 Issued at 2200Z on 26 Dec 2009
IA.  Analysis of Solar Active Regions and Activity from  25/2100Z
to 26/2100Z:  Solar activity was very low.  New Region 1039 (S26E45)
was numbered today as a three-spot, Bxo-beta spot group. During the
period, several low-level B-class flares occurred from Region 1039.
The largest of these was a B4.8 at 1657Z.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low, with a slight chance for an isolated C-class flare.
IIA.  Geophysical Activity Summary 25/2100Z to 26/2100Z:
The geomagnetic field was quiet.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet for the next three days (27-29 December).
