:Product: 1126RSGA.txt :Issued: 2007 Nov 26 2203 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 330 Issued at 2200Z on 26 Nov 2007 IA. Analysis of Solar Active Regions and Activity from 25/2100Z to 26/2100Z: Solar activity was at very low levels. Region 975 (N03W38) decayed to an AXX spot group. IB. Solar Activity Forecast: Solar activity is expected to remain at very low levels. IIA. Geophysical Activity Summary 25/2100Z to 26/2100Z: The geomagnetic field was at quiet to unsettled levels, due to the continued influence of a coronal hole high speed stream. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels again today. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at mostly quiet levels for the forecast period (27 to 29 November). III.
