:Product: 20021112RSGA.txt :Issued: 2002 Nov 12 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 316 Issued at 2200Z on 12 Nov 2002 IA. Analysis of Solar Active Regions and Activity from 11/2100Z to 12/2100Z: Solar activity has been moderate. A long duration C7/0f event was observed at 11/2255 UTC from Region 191 (S18E25). An optically uncorrelated Type II radio sweep was observed at 12/0356 UTC. The LASCO/SOHO imagery indicates this activity may have originated from Region 188 (N10W61). Region 180 (S11W82) produced an M2/1n event at 12/1856 UTC. A new region was numbered today as Region 193 (S02E21). IB. Solar Activity Forecast: Solar activity is expected to be low to moderate. Region 180 and 191 have potential to produce an M-class event. IIA. Geophysical Activity Summary 11/2100Z to 12/2100Z: The geomagnetic field has been predominately quiet to unsettled with one period of active conditions observed at high latitudes at 12/1500 UTC. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be unsettled to active for 13-14 November as a possible result of the CME associated with the M1/1n observed 11/1620 UTC. Quiet to unsettled conditions are expected to return on 15 November. III. Event Probabilities 13 Nov-15 Nov Class M 80/70/50 Class X 15/10/01 Proton 10/05/01 PCAF green IV.
