Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 330 Issued at 2200Z on 26 Nov 2009
IA.  Analysis of Solar Active Regions and Activity from  25/2100Z
to 26/2100Z:  Solar activity was very low.  The visible solar disk
was spotless.  No flares were observed during the past 24 hours.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 25/2100Z to 26/2100Z:
The geomagnetic field was mostly quiet.  One period of unsettled
conditions was observed at mid-latitude reported at 26/1200Z. 
Observations from the ACE spacecraft show a continued decrease in
solar wind speeds.  Velocities ranged from around 430 km/s at the
beginning of the period to around 375 km/s at forecast time.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be predominantly quiet for the next three days (27-29
November).
