Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 336 Issued at 2200Z on 01 Dec 2000
IA.  Analysis of Solar Active Regions and Activity from  30/2100Z
to 01/2100Z:  Solar activity was low. Isolated C-class flares
occurred, with Regions 9246 (S12E04), 9242 (N21W28), and 9240
(N09W43) contributing. The nine spot groups on the disk were stable
or declining, as little of significance occurred. There was limb
activity associated with now-departed Region 9236 (N20). The East
Limb was quiet.
IB.  Solar Activity Forecast:  Solar activity is expected to be low
to moderate.
IIA.  Geophysical Activity Summary 30/2100Z to 01/2100Z:
The geomagnetic field was quiet to unsettled.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be predominantly unsettled throughout the period.
