Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 350 Issued at 2200Z on 15 Dec 2000
IA.  Analysis of Solar Active Regions and Activity from  14/2100Z
to 15/2100Z:  Solar activity was low.  Maximum activity continues to
be sporadic minor C-class events.
IB.  Solar Activity Forecast:  Solar activity is expected to be low,
with the chance for an isolated M-class event.
IIA.  Geophysical Activity Summary 14/2100Z to 15/2100Z:
The geomagnetic field has been quiet at all latitudes for the past 24
hours.  The greater than 2 MeV flux continued its recent daily
fluctuation between low and moderate levels.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be low, with isolated periods of unsettled conditions,
for the next three days.
