:Product: 0307RSGA.txt :Issued: 2007 Mar 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 066 Issued at 2200Z on 07 Mar 2007 IA. Analysis of Solar Active Regions and Activity from 06/2100Z to 07/2100Z: Solar activity was very low. Region 944 has rotated off the visible disk. Region 945 (S07W56) no longer exhibits visible spots. At approximately 07/0100Z a slow moving CME was observed on the west limb apparently from the backside. Due to the position and speed of this CME it is not expected to be geoeffective. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z: The geomagnetic field has been unsettled to active. Solar wind speed remains elevated near 600 km/s due to a recurrent coronal hole high speed stream. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels today. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled 08 - 10 March . III.
