:Product: 0707RSGA.txt :Issued: 2009 Jul 07 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 188 Issued at 2200Z on 07 Jul 2009 IA. Analysis of Solar Active Regions and Activity from 06/2100Z to 07/2100Z: Solar activity was very low. No x-ray flares were observed during the past 24 hours. Region 1024 (S27W39) continued to decay and activity from the region was significantly reduced. The remainder of the disk was quiet and stable. IB. Solar Activity Forecast: Solar activity is expected to remain very low with a slight chance for an isolated C-flare from Region 1024. IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z: The geomagnetic field was quiet during the past 24 hours. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet on day one (8 July). An increase to quiet to unsettled is expected for day two (9 July) due to possible coronal hole effects. Conditions should be predominately quiet for day three (10 July). III.
