:Product: 0212RSGA.txt :Issued: 2009 Feb 12 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 043 Issued at 2200Z on 12 Feb 2009 IA. Analysis of Solar Active Regions and Activity from 11/2100Z to 12/2100Z: Solar activity was very low. Region 1012 (S05E48) produced todays only flare, a B4 at 1619Z. The event was associated with a relatively symmetrical wave that was well defined in the STEREO-B EUVI 195 imagery. The remainder of the disk was quiet and stable. IB. Solar Activity Forecast: Solar activity is expected to be very low for the next three days (13-15 February). IIA. Geophysical Activity Summary 11/2100Z to 12/2100Z: The geomagnetic field was quiet during the past 24 hours. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet for the first day (13 February) and partway through the second day (14 February). During the latter part of the second day and continuing through the third day (15 February) a favorably positioned coronal hole is expected to increase activity to unsettled levels with a chance for active periods.
