Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 363 Issued at 2200Z on 28 Dec 2008
IA.  Analysis of Solar Active Regions and Activity from  27/2100Z
to 28/2100Z:  Solar activity was very low with no flares observed. 
The visible disk remained spotless.  SOHO Lasco C2 imagery observed
the first of four, weak CMEs off the northeast limb beginning at
27/0530Z.  The last of these CMEs was observed in C3 imagery at
27/1818Z.  None of these CMEs are expected to be geoeffective.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 27/2100Z to 28/2100Z:
The geomagnetic field was quiet at all latitudes.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet throughout the forecast period (29 - 31
December).
