Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 341 Issued at 2200Z on 07 Dec 2010
IA.  Analysis of Solar Active Regions and Activity from  06/2100Z
to 07/2100Z:  Solar activity was very low.  Regions 1131 (N31E03) and
1133 (N15E31) remained quiet and stable.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low for the next 3 days (08-10 December).
IIA.  Geophysical Activity Summary 06/2100Z to 07/2100Z:
The geomagnetic field was quiet.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be mostly quiet for days 1 and 2 (08-09 December), and
quiet to unsettled with the chance for active conditions on day 3
(10 December). The increase in activity is due to the anticipated
effects of a recurrent coronal hole.
