:Product: 1130RSGA.txt :Issued: 2010 Nov 30 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 334 Issued at 2200Z on 30 Nov 2010 IA. Analysis of Solar Active Regions and Activity from 29/2100Z to 30/2100Z: Solar activity was very low during the past 24 hours. A CME from the NE quadrant was observed in SDO/AIA images at approximately 30/1830 UTC. Further analysis is required to determine if the CME will be geoeffective. IB. Solar Activity Forecast: Solar activity is expected to be very low with a chance for C-class activity from Region 1130 (N12W27). IIA. Geophysical Activity Summary 29/2100Z to 30/2100Z: The geomagnetic field was quiet during the past 24 hours. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be mostly quiet for days one and two (01-02 Dec) as the effects from a coronal hole high-speed stream continue to subside. Quiet to unsettled conditions with a slight chance for isolated active periods are expected on day three (03 Dec) due to possible effects from a CME associated with the disappearing filament observed early on 29 November.
