:Product: 0630RSGA.txt :Issued: 2007 Jun 30 2202 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 181 Issued at 2200Z on 30 Jun 2007 IA. Analysis of Solar Active Regions and Activity from 29/2100Z to 30/2100Z: Solar activity was very low. Region 961 (S12E09) has developed in size and complexity, but has not produced any significant activity. Region 962 (S10E37) has decayed into a simple Alpha-class spot group. IB. Solar Activity Forecast: Solar activity is expected to be very low. There is a slight chance of an isolated C-class flare from Region 961. IIA. Geophysical Activity Summary 29/2100Z to 30/2100Z: The geomagnetic field was quiet to unsettled. Solar wind speed has been steadily decreasing, but remains slightly elevated due to the coronal hole high speed stream. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled for the next three days (01 - 03 July). III.
