Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 309 Issued at 2200Z on 05 Nov 2006

IA. Analysis of Solar Active Regions and Activity from 04/2100Z to 05/2100Z: Solar activity was low. Region 921 (S08W24) produced two C-class flares. The largest of these was a C3/Sf flare at 05/1227Z. A Type II radio sweep was reported at 05/1730Z. Solar observatories reported estimated shock speeds ranging from 1089 to 1541 km/sec. Although no significant flare activity was observed at this time, H-alpha imagery indicates a DSF may have occurred.

IB. Solar Activity Forecast: Solar activity is expected to be very low. There remains a chance of an isolated C-class flare from Region 921.

IIA. Geophysical Activity Summary 04/2100Z to 05/2100Z:

The geomagnetic field was quiet to unsettled. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be predominantly quiet.
