:Product: 0220RSGA.txt :Issued: 2007 Feb 20 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 051 Issued at 2200Z on 20 Feb 2007 IA. Analysis of Solar Active Regions and Activity from 19/2100Z to 20/2100Z: Solar activity was very low. Region 942 (S11E15) and 943 (S12W10) are the two numbered regions on the visible disk. Both retain a beta magnetic configuration. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 19/2100Z to 20/2100Z: The geomagnetic field was quiet. The greater than 2 MeV electrons at geosynchronous orbit were at high levels. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels. III. Event Probabilities 21 Feb-23 Feb Class M 01/01/01 Class X 01/01/01 Proton 01/01/01 PCAF green IV.
