:Product: 0829RSGA.txt :Issued: 2011 Aug 29 2200 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 241 Issued at 2200Z on 29 Aug 2011 IA. Analysis of Solar Active Regions and Activity from 28/2100Z to 29/2100Z: Solar activity was low. Occasional C-class x-ray flares occurred. The largest flare was a C3 at 29/0721Z from an area just beyond the northeast limb. Visible disk regions were either stable or declining. There were no Earth-directed CMEs observed during the period. No new regions were numbered. IB. Solar Activity Forecast: Solar activity is expected to be very low during the period (30 August - 01 September) with a chance for more C-class activity from the area just beyond the northeast limb. IIA. Geophysical Activity Summary 28/2100Z to 29/2100Z: Geomagnetic field activity was at quiet to unsettled levels. IIB. Geophysical Activity Forecast: Geomagnetic field activity is expected to be at mostly quiet levels through the period (30 August - 01 September). III.
