:Product: 0709RSGA.txt :Issued: 2010 Jul 09 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 190 Issued at 2200Z on 09 Jul 2010 IA. Analysis of Solar Active Regions and Activity from 08/2100Z to 09/2100Z: Solar activity was low. New Region 1087 (N18E72) was numbered today and produced three C-class events. The largest of these was a C3/Sf at 09/1951Z. IB. Solar Activity Forecast: Solar activity is expected to be very low to low. There is a chance for a C-class flare, and a slight chance for a M-class event, from Region 1087. IIA. Geophysical Activity Summary 08/2100Z to 09/2100Z: The geomagnetic field was quiet. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels today. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be predominantly quiet for the next three days (10-12 July). III.
