:Product: 0610RSGA.txt :Issued: 2006 Jun 10 2204 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 161 Issued at 2200Z on 10 Jun 2006 IA. Analysis of Solar Active Regions and Activity from 09/2100Z to 10/2100Z: Solar activity was very low. Today's activity consisted of a single B-class flare from Region 892 (S07W14) at 1639Z. The region remains beta-gamma but appears stable and generally unchanged compared to yesterday. Region 893 (S02E10) has decreased somewhat in area. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic field was quiet to unsettled. The solar wind velocity remains somewhat elevated, but is decreasing steadily and has not enhanced geomagnetic activity. The greater than 2 MeV electron flux reached high levels during the past 24 hours. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled for the next three days (11 - 13 June). III.
