Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 338 Issued at 2200Z on 03 Dec 2000
IA.  Analysis of Solar Active Regions and Activity from  02/2100Z
to 03/2100Z:  Solar activity remained at the low level. Very little
eruptive activity occurred, but the disk did experience considerable
change from yesterday. Six new regions were numbered. They are: 9250
(S11W80), 9251 (S22W34), 9252 (S02W36), 9253 (S14E11), 9254
(N10E59), and 9255 (N21E64). All are simple and small.
IB.  Solar Activity Forecast:  Solar activity is expected to persist
at the low level.
IIA.  Geophysical Activity Summary 02/2100Z to 03/2100Z:
The geomagnetic field was quiet to active. A prolonged period of
southward IMF caused the weak disturbance during the latter half of
the interval.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled.
