:Product: 0708RSGA.txt :Issued: 2009 Jul 08 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 189 Issued at 2200Z on 08 Jul 2009 IA. Analysis of Solar Active Regions and Activity from 07/2100Z to 08/2100Z: Solar activity was very low. Region 1024 (S25W52) produced four B-class flares during the past 24 hours. The region underwent minor changes and is currently an E type sunspot group with a simple beta magnetic configuration. IB. Solar Activity Forecast: Solar activity is expected to remain very low with a slight chance for an isolated C-class flare. IIA. Geophysical Activity Summary 07/2100Z to 08/2100Z: Geomagnetic activity was quiet during the past 24 hours. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled for day one (9 July) due to possible coronal hole effects. Activity is expected to return to quiet levels on day two (10 July). Activity is expected to be quiet to unsettled on day three (11 July), also due to possible coronal hole effects. III.
