Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 365 Issued at 2200Z on 31 Dec 2009
IA.  Analysis of Solar Active Regions and Activity from  30/2100Z
to 31/2100Z:  Solar activity was very low. Region 1039 (S28W21) grew
in both sunspot count and white light area coverage and produced
several low-level B-flares. This region remains a D-type sunspot
group with a beta magnetic classification.
IB.  Solar Activity Forecast:  Solar activity is expected to be very 
low to low. There is a slight chance of an isolated C-flare and
M-flare from Region 1039.
IIA.  Geophysical Activity Summary 30/2100Z to 31/2100Z:
The geomagnetic field was quiet.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet for the next three days (01 - 03 January).
