Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 354 Issued at 2200Z on 19 Dec 2008
IA.  Analysis of Solar Active Regions and Activity from  18/2100Z
to 19/2100Z:  Solar activity was very low.  The visible disk remained
spotless.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 18/2100Z to 19/2100Z:
The geomagnetic field was at quiet levels.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at quiet levels for 20 - 21 December.  Quiet to
unsettled conditions are expected for 22 December.  The increase in
activity is forecast due to a recurrent coronal hole high speed
stream.
