:Product: 20010207RSGA.txt :Issued: 2001 Feb 07 2200 UTC # Prepared jointly by the U.S. Dept. of Commerce, NOAA, # Space Environment Center and the U.S. Air Force. # Joint USAF/NOAA Report of Solar and Geophysical Activity SDF Number 038 Issued at 2200Z on 07 Feb 2001 IA. Analysis of Solar Active Regions and Activity from 06/2100Z to 07/2100Z: Solar activity was low. Only a few C-class flares occurred, all without reported optical flares. All of the sunspot groups currently on the disk are relatively small and magnetically simple. New Region 9343 (N03E08) was numbered. IB. Solar Activity Forecast: Solar activity is expected to be low. IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z: The geomagnetic field was quiet to unsettled. Solar wind information suggests that the high speed stream observed on 06 Feb is passing, returning solar wind parameters to nominal levels. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled. III. Event Probabilities 08 Feb-10 Feb Class M 20/20/20 Class X 01/01/01 Proton 01/01/01 PCAF green IV.
