:Product: 1110RSGA.txt :Issued: 2007 Nov 10 2202 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 314 Issued at 2200Z on 10 Nov 2007 IA. Analysis of Solar Active Regions and Activity from 09/2100Z to 10/2100Z: Solar activity was very low. The visible disk remained spotless and no flares were observed. IB. Solar Activity Forecast: Solar activity is expected to remain very low IIA. Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic field was quiet to unsettled. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be mostly quiet on days 1 and 2 of the forecast period (11-12 November). Activity is expected to increase to unsettled to occasionally active levels at mid lititudes on day 3 (13 November), with a slight chance for minor storming at high latitudes, as a recurrent coronal hole becomes geoeffective.
