:Product: 1201RSGA.txt :Issued: 2008 Dec 01 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 336 Issued at 2200Z on 01 Dec 2008 IA. Analysis of Solar Active Regions and Activity from 30/2100Z to 01/2100Z: Solar activity was very low. No flares were observed. The visible disk was spotless. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 30/2100Z to 01/2100Z: Geomagnetic field activity was at quiet levels at all latitudes. IIB. Geophysical Activity Forecast: Geomagnetic field activity is expected to be at quiet levels during days 1 - 2 (02 - 03 December). Activity is expected to increase to quiet to unsettled levels on day 3 (04 December) as a recurrent coronal hole high-speed stream begins to disturb the field. III.
