Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 337 Issued at 2200Z on 03 Dec 2001
IA.  Analysis of Solar Active Regions and Activity from  02/2100Z
to 03/2100Z:  Solar activity has been moderate.  The NOAA/SXI test
imagery observed an M2 event from Region 9714 at 02/2206 UTC as it
rotated around the southwest limb of the sun.  Region 9715 (N04W49)
continues to show a slight decay from yesterday.  New Region 9727
(S22E68) was numbered today.
IB.  Solar Activity Forecast:  Solar activity is expected to be low
to moderate.  Isolated major flares are possible from Regions 9715
and 9718 (S07E03).
IIA.  Geophysical Activity Summary 02/2100Z to 03/2100Z:
The geomagnetic field was quiet to unsettled.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled.  Isolated active conditions are
possible for 04 - 05 December due to coronal hole effects.
