:Product: 0707RSGA.txt :Issued: 2007 Jul 07 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 188 Issued at 2200Z on 07 Jul 2007 IA. Analysis of Solar Active Regions and Activity from 06/2100Z to 07/2100Z: Solar activity was low. New Region 963 (S09E83) rotated into view today and produced several B-class flares as well as one C-class flare at 1430Z. Region 961 (S08W86) was quiet and stable and is rotating off the disk. IB. Solar Activity Forecast: Solar activity is expected to be very low to low for the next three days (08-10 July). IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z: 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 quiet for the next two days (08-09 July). An increase to unsettled levels is expected sometime on the third day (10 July) in response to a recurrent coronal hole. III.
