:Product: 0824RSGA.txt :Issued: 2007 Aug 24 2203 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 236 Issued at 2200Z on 24 Aug 2007 IA. Analysis of Solar Active Regions and Activity from 23/2100Z to 24/2100Z: Solar activity has been low. Region 969 (S05E35) produced an impulsive C2/Sn event at 24/0754 UTC. IB. Solar Activity Forecast: Solar activity is expected to be very low to low. Region 969 could possibly produce an isolated C-class flare. IIA. Geophysical Activity Summary 23/2100Z to 24/2100Z: The geomagnetic field has been quiet. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled with isolated active periods. The increase in activity is expected in response to a recurrent coronal hole.
