:Product: 0705RSGA.txt :Issued: 2010 Jul 05 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 186 Issued at 2200Z on 05 Jul 2010 IA. Analysis of Solar Active Regions and Activity from 04/2100Z to 05/2100Z: Solar activity was very low. New Region 1086 (N18W53) formed on the disk as a simple beta sunspot group. A CME was observed lifting off behind the NE limb late in the period. SOHO LASCO C2 imagery first observed this event at 05/1754Z, as well as STEREO-B COR2 imagery shortly afterwards at 05/1810Z. The CME appears to be associated with old Region 1082 (N27, L=305) due to return on 10 July. IB. Solar Activity Forecast: Solar activity is expected to remain at very low levels. IIA. Geophysical Activity Summary 04/2100Z to 05/2100Z: The geomagnetic field was quiet. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels during the past 24 hours. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at mostly quiet levels during the next three days (06 - 08 July). III.
