:Product: 20040901RSGA.txt :Issued: 2004 Sep 01 2200 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 245 Issued at 2200Z on 01 Sep 2004 IA. Analysis of Solar Active Regions and Activity from 31/2100Z to 01/2100Z: Solar activity has been very low. A faint full-halo CME was observed on LASCO imagery beginning at 1255Z, although the CME is most likely backsided. New Region 667 (S09E76) is rotating onto the visible disk from the east limb. IB. Solar Activity Forecast: Solar activity is expected to be very low to low. IIA. Geophysical Activity Summary 31/2100Z to 01/2100Z: Geomagnetic activity has been quiet to unsettled. IIB. Geophysical Activity Forecast: Geomagnetic activity is expected to be quiet to unsettled. On 03 September, isolated active conditions are possible due to a glancing blow from a CME shock associated with the M1.4 flare from Region 663 on the 31 August at 0538Z. III.
