:Product: 1113RSGA.txt :Issued: 2007 Nov 13 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 317 Issued at 2200Z on 13 Nov 2007 IA. Analysis of Solar Active Regions and Activity from 12/2100Z to 13/2100Z: Solar activity was very low. IB. Solar Activity Forecast: Solar activity is expected to remain very low. IIA. Geophysical Activity Summary 12/2100Z to 13/2100Z: The geomagnetic field was quiet to unsettled as a coronal hole high speed stream became geoeffective. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to remain unsettled to occasionally active, with isolated minor storm periods possible at high latitudes. Activity begins to decrease to unsettled to quiet levels on day 3 (16 Nov) as the coronal hole rotates out of a geoeffective position. III.
