:Product: 20001114RSGA.txt :Issued: 2000 Nov 14 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 319 Issued at 2200Z on 14 Nov 2000 IA. Analysis of Solar Active Regions and Activity from 13/2100Z to 14/2100Z: Solar activity increased to moderate levels. An M1 X-ray flare occurred at 14/1634 UTC. No ground-based optical reports were received for this flare, but SOHO/EIT images indicate that this flare originated near the northeast limb, possibly from newly numbered Region 9233 (N13E76). Region 9231 (S24E56) increased in spot count and area during the day. It produced occasional subflares, the largest of which was a C7/2n at 14/0806 UTC. A Type IV radio sweep began at 14/0831 UTC and may have been associated with the C7/2n flare. A Type II radio sweep occurred at 14/0902 UTC. Minor spot growth occurred in Region 9227 (S10W28). IB. Solar Activity Forecast: Solar activity is expected to be at low to moderate levels. Isolated M-class flare activity is possible. IIA. Geophysical Activity Summary 13/2100Z to 14/2100Z: Geomagnetic field activity was at mostly quiet levels. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels during most of the period. IIB. Geophysical Activity Forecast: Geomagnetic field activity is expected to be at quiet to unsettled levels. The greater than 2 MeV electron flux at geosynchronous orbit is expected to decline to normal to moderate levels during the latter half of the period. III.
