:Product: 1202RSGA.txt :Issued: 2010 Dec 02 2200 UTC # Prepared jointly by the U.S. Dept. of Commerce, NOAA, # Space Weather Prediction Center and the U.S. Air Force. # Joint USAF/NOAA Report of Solar and Geophysical Activity SDF Number 336 Issued at 2200Z on 02 Dec 2010 IA. Analysis of Solar Active Regions and Activity from 01/2100Z to 02/2100Z: Solar activity was very low during the past 24 hours. New Region 1131 (N30E68) was numbered during the period and is an Hsx-Alpha type spot group. Region 1130 (N14W52) remained stable and quiet throughout the period. IB. Solar Activity Forecast: Solar activity is expected to be very low for the next three days (03-05 December) with a chance for isolated C-class flares from Region 1130. IIA. Geophysical Activity Summary 01/2100Z to 02/2100Z: The geomagnetic field was quiet during the past 24 hours. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled with a chance for isolated active periods during the next three days (03-05 December) due to possible effects from a CME associated with the disappearing filament observed on 29 November. The CME observed near N15E40 on 30 November may also contribute to elevated activity throughout the period. III.
