Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 352 Issued at 2200Z on 17 Dec 2008
IA.  Analysis of Solar Active Regions and Activity from  16/2100Z
to 17/2100Z:  Solar activity was very low.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 16/2100Z to 17/2100Z:
The geomagnetic field was predominantly quiet.  The ACE spacecraft
indicated a possible CME signature from a filament that erupted on
12 December.  There was a slight increase in wind speed and density
with minor fluctuations in the IMF.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at quiet levels for the next three days (18-20
December)
