:Product: 20020502RSGA.txt :Issued: 2002 May 02 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 122 Issued at 2200Z on 02 May 2002 IA. Analysis of Solar Active Regions and Activity from 01/2100Z to 02/2100Z: Solar activity was low. Only a few small C-class flares occurred. Region 9934 (S18E62) is the largest and probably the most magnetically complex sunspot group on the disk. The region appears to contain some mixed polarities, and possibly a delta configuration, but is still too close to the limb for certainty. New Regions 9935 (S18E33) and 9936 (S15E42) were numbered. IB. Solar Activity Forecast: Solar activity is expected to be low to moderate. C-class events are possible from a number of regions. Region 9934 appears to be the most capable of M-class activity. IIA. Geophysical Activity Summary 01/2100Z to 02/2100Z: The geomagnetic field was quiet to unsettled. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled.
