SDF Number 359 Issued at 2200Z on 25 Dec 2005
IA.  Analysis of Solar Active Regions and Activity from  24/2100Z
to 25/2100Z:  Solar activity was low. New Region 842 (S06E30)
produced a C1 flare at 25/1014 UTC.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low to low.
IIA.  Geophysical Activity Summary 24/2100Z to 25/2100Z:
The geomagnetic field was quiet to unsettled.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled on 26 December. On 27 and 28
December, unsettled to active conditions are expected with the
possibility of minor storm periods due to a recurrent coronal hole
high speed stream.
