Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 331 Issued at 2200Z on 27 Nov 2007
IA.  Analysis of Solar Active Regions and Activity from  26/2100Z
to 27/2100Z:  Solar activity was very low. No flares occurred during
the past 24 hours. Region 975 (N03W50) has decayed to spotless
plage.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 26/2100Z to 27/2100Z:
The geomagnetic field was mostly quiet. Solar wind speed steadily
declined throughout the period with day-end values around 440 km/s.
The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels during the past 24 hours.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet for the next three days (28-30 November).
