Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 340 Issued at 2200Z on 05 Dec 2000
IA.  Analysis of Solar Active Regions and Activity from  04/2100Z
to 05/2100Z:  Solar activity has been low.  A long duration C1 X-ray
flare occurred at 05/1823Z. An examination of SOHO/EIT images
suggest that it originated from Region 9246 (S17E51).  The remainder
of the solar disk was mostly stable through the period.
IB.  Solar Activity Forecast:  Solar activity is expected to be low
for the forecast period.
IIA.  Geophysical Activity Summary 04/2100Z to 05/2100Z:
The geomagnetic field was predominately quiet the past 24 hours.  One
period of active conditions was observed at mid latitudes at
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled for the forecast period.
