:Product: 0507RSGA.txt :Issued: 2007 May 07 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 127 Issued at 2200Z on 07 May 2007 IA. Analysis of Solar Active Regions and Activity from 06/2100Z to 07/2100Z: Solar activity has been very low. IB. Solar Activity Forecast: Solar activity is expected to be very low to low. IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z: The geomagnetic field ranged from quiet to unsettled with one period of minor storming. Real-time solar wind data are consistent with the onset of a high speed solar wind stream. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels again today. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled on 08 May. Isolated active periods are possible due to a geoeffective recurrent coronal hole high speed stream. The geomagnetic field is expected to be predominately quiet 09 - 10 May. III.
