:Product: 20020922RSGA.txt :Issued: 2002 Sep 22 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 265 Issued at 2200Z on 22 Sep 2002 IA. Analysis of Solar Active Regions and Activity from 21/2100Z to 22/2100Z: Solar activity was low. A few C-class flares occurred. Region 119 (S14W49) remains the largest, most complex sunspot group on the disk but appears to have simplified somewhat. Four new Regions were numbered: 129 (N25E54), 130 (N06E52), 131 (S07E35), and 132 (N18W01). IB. Solar Activity Forecast: Solar activity is expected to be low to moderate. Region 119 seems to be the most capable area for M-class activity. IIA. Geophysical Activity Summary 21/2100Z to 22/2100Z: The geomagnetic field was quiet to unsettled. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled. III. Event Probabilities 23 Sep-25 Sep Class M 50/50/50 Class X 05/05/05 Proton 05/05/05 PCAF green IV.
