:Product: 20021116RSGA.txt :Issued: 2002 Nov 16 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 320 Issued at 2200Z on 16 Nov 2002 IA. Analysis of Solar Active Regions and Activity from 15/2100Z to 16/2100Z: Solar activity was low. Region 191 (S18W28) produced a C8/Sf flare at 16/1359 UTC. Region 191 remains the most complex region on the disk with a beta-gamma-delta magnetic configuration and a slight increase in penumbral coverage. Region 192 (N12W61) has also shown some increase in penumbral coverage but only produced a minor C5 flare and a number of sub flares. Region 195 (S16E41) simplified to a beta-gamma magnetic configuration but some polarity mixing is evident in the trailing spots. SOHO/LASCO C2 imagery indicated a faint full halo CME, first appearing in the C2 field of view at 16/0712 UTC. The source of this CME may be a C1.9 flare from Region 191 at 16/0636 UTC. IB. Solar Activity Forecast: Solar activity is expected to be low to moderate. Region 191, Region 192 and Region 195 have the potential for M-class activity. IIA. Geophysical Activity Summary 15/2100Z to 16/2100Z: The geomagnetic field was quiet to unsettled. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to isolated active conditions. Coronal hole effects are expected during the period. III.
