:Product: 1030RSGA.txt :Issued: 2012 Oct 30 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 304 Issued at 2200Z on 30 Oct 2012 IA. Analysis of Solar Active Regions and Activity from 29/2100Z to 30/2100Z: Solar activity was very low. Region 1598 (S11W51) produced a B8 flare at 0137Z. A filament eruption occurred from 0640Z to 0855Z near S32E07 with a heliographic extent of 24 degrees. IB. Solar Activity Forecast: Solar activity is expected to be very low with a chance for low level activity. IIA. Geophysical Activity Summary 29/2100Z to 30/2100Z: Geomagnetic field activity was at quiet levels. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be mostly quiet on day 1 (31 October), increasing to a chance for active levels with the arrival of the 27 and 28 October CMEs late in the day. Unsettled to active with a chance for minor storm levels are expected on day 2 (1 November) from CME effects. On day 3 (2 November) conditions are expected to decline to quiet to unsettled with a chance for active as CME effects subside. III.
