Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 349 Issued at 2200Z on 15 Dec 2009
IA.  Analysis of Solar Active Regions and Activity from  14/2100Z
to 15/2100Z:  Solar activity has been very low.  Numerous low-level
B-class events occurred, the largest being a B4 at 2339Z from Region
1035 (N30W05).  Region 1035 has grown steadily during the past 24
hours and is currently a 20 spot Dai Beta group with an area of
approximately 150 millionths.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low to low.  There is a chance for an isolated C-class event from
Region 1035.
IIA.  Geophysical Activity Summary 14/2100Z to 15/2100Z:
The geomagnetic field has been quiet.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet for the next three days (16-18 December).
