Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 343 Issued at 2200Z on 09 Dec 2010
IA.  Analysis of Solar Active Regions and Activity from  08/2100Z
to 09/2100Z:  Solar activity was very low.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low for the next 3 days (10-12 December).
IIA.  Geophysical Activity Summary 08/2100Z to 09/2100Z:
The geomagnetic field was mostly quiet.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet for the first half of day 1 (10 December). 
Mostly unsettled conditions with a chance for isolated active
periods are expected through the remainder of the period due to a
recurrent coronal hole.
