:Product: 20001130RSGA.txt :Issued: 2000 Nov 30 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 335 Issued at 2200Z on 30 Nov 2000 IA. Analysis of Solar Active Regions and Activity from 29/2100Z to 30/2100Z: Solar activity was moderate. Two M-class events occurred -- an M1 at 0925 UTC, and recently an M1 at 2038 UTC. Region 9246 (S12E19) produced subfaint optical flares corresponding to the x-ray bursts. This region has grown in white light and h-alpha throughout the period, and is the most volatile region of the ten on the disk. Two new regions were born on the disk, 9248 (N04W17) and 9249 (N11E45). Region 9236 (N20W89) is making an uneventful west limb passage. IB. Solar Activity Forecast: Solar activity is expected to be moderate. Region 9246 should produce occasional M-class activity. IIA. Geophysical Activity Summary 29/2100Z to 30/2100Z: The geomagnetic field was quiet to unsettled. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to persist at quiet to unsettled levels for the next three days. III.
