:Product: Report of Solar-Geophysical Activity :Issued: 2009 Jan 11 2201 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 011 Issued at 2200Z on 11 Jan 2009 IA. Analysis of Solar Active Regions and Activity from 10/2100Z to 11/2100Z: Solar activity was very low. Region 1010 (N18E05) retained its beta magnetic configuration, producing only low-level flares during the past 24 hours. IB. Solar Activity Forecast: Solar activity is expected to be very low. There is a slight chance for a C-class flare from Region 1010. 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 predominantly quiet for the next three days (12 - 14 January). III.
