:Product: 0713RSGA.txt :Issued: 2007 Jul 13 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 194 Issued at 2200Z on 13 Jul 2007 IA. Analysis of Solar Active Regions and Activity from 12/2100Z to 13/2100Z: Solar activity was very low. No significant flares occurred during the past 24 hours. New Region 964 (N04W30) is classified as a beta spot group. Region 963 (S06E01) continues to slowly decay. IB. Solar Activity Forecast: Solar activity is expected to be very low, with a slight chance for an isolated C-class flare from Region 963 or 964. IIA. Geophysical Activity Summary 12/2100Z to 13/2100Z: The geomagnetic field was quiet. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled, with a chance for isolated active periods on 14-15 July due to a recurrent coronal hole. III.
