:Product: 0211RSGA.txt :Issued: 2007 Feb 11 2203 UTC # Prepared jointly by the U.S. Dept. of Commerce, NOAA, # Space Environment Center and the U.S. Air Force. # Joint USAF/NOAA Report of Solar and Geophysical Activity SDF Number 042 Issued at 2200Z on 11 Feb 2007 IA. Analysis of Solar Active Regions and Activity from 10/2100Z to 11/2100Z: Solar activity was very low. There are no regions with spots on the visible disk. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 10/2100Z to 11/2100Z: The geomagnetic field was quiet. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be unsettled to active with a possibility for isolated periods of minor storming from 12 - 14 February. A coronal hole high speed stream is anticipated to rotate into a geoeffective position for that period. III.
