:Product: 0306RSGA.txt :Issued: 2008 Mar 06 2203 UTC # Prepared jointly by the U.S. Dept. of Commerce, NOAA, # Space Weather Prediction Center and the U.S. Air Force. # Joint USAF/NOAA Report of Solar and Geophysical Activity SDF Number 066 Issued at 2200Z on 06 Mar 2008 IA. Analysis of Solar Active Regions and Activity from 05/2100Z to 06/2100Z: Solar activity remains at very low levels. Region 984 (S08W80) is a small beta sunspot group rotating quietly around the west limb. The rest of the solar disk and limb is very quiet. IB. Solar Activity Forecast: Solar activity is expected to continue at very low levels. IIA. Geophysical Activity Summary 05/2100Z to 06/2100Z: The geomagnetic field was quiet. The greater than 2 MeV electron flux at geosynchronous orbit briefly exceeded high levels today. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to range from quiet to minor storm levels over the next three days. Quiet to unsettled conditions are expected on 7 March. A recurring high speed coronal hole stream will rotate into a geoeffective position on 8 March, and produce occasional active to minor storm periods on 8 and 9 March. III.
