:Product: 0310RSGA.txt :Issued: 2007 Mar 10 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 069 Issued at 2200Z on 10 Mar 2007 IA. Analysis of Solar Active Regions and Activity from 09/2100Z to 10/2100Z: Solar activity was at very low levels. No flares were recorded during the period. Region 946 (N10W46) is a six spot Bxo beta group that was numbered today. IB. Solar Activity Forecast: Solar activity is expected to remain at very low levels. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels again today. IIA. Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic field was at quiet levels. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet on 11 March. Active to isolated minor storm conditions are expected on 12 and 13 March due to a recurrent coronal hole high speed stream. III.
