Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 359 Issued at 2200Z on 25 Dec 2006
IA.  Analysis of Solar Active Regions and Activity from  24/2100Z
to 25/2100Z:  Solar activity was very low. New Regions 931 (S08E55)
and 932 (S07E35) were numbered today. Region 932 was responsible for
several low level B-flares since its emergence. This region is
classified as a beta magnetic group.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low with a slight chance for an isolated C-flare from Region 932.
IIA.  Geophysical Activity Summary 24/2100Z to 25/2100Z:
The geomagnetic field was mostly quiet. The greater than 2 MeV
electron flux at geosynchronous orbit was at high levels again
today.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled on 26 December. On 27 December,
unsettled to active conditions are expected. Quiet to unsettled
levels are expected to return by 28 December.
