:Product: 0608RSGA.txt :Issued: 2007 Jun 08 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 159 Issued at 2200Z on 08 Jun 2007 IA. Analysis of Solar Active Regions and Activity from 07/2100Z to 08/2100Z: Solar activity continued low. Region 960 (S08W17), the most prominent of the spotted regions visible, continues to simplify and decay. It has produced frequent small C-class activity through the interval. The other two spotted regions have been quiet. IB. Solar Activity Forecast: Solar activity is expected to be low. Region 960 retains the potential for an isolated M-class flare. IIA. Geophysical Activity Summary 07/2100Z to 08/2100Z: The geomagnetic field has been quiet. The GOES greater than 2 MeV electron flux was at high levels once again. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to persist at quiet conditions through the forecast period. III.
