:Product: 0314RSGA.txt :Issued: 2010 Mar 14 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 073 Issued at 2200Z on 14 Mar 2010 IA. Analysis of Solar Active Regions and Activity from 13/2100Z to 14/2100Z: Solar activity has been at low levels for the past 24 hours. Region 1054 (N14E01) produced two C-class flares. The C-class event at 13/2349Z was a long duration C1.5 SF flare associated with a partial halo CME and a sympathetic disappearing filament. Region 1054 has shown little growth and still magnetically classified as a Beta-Gamma. No new regions were numbered today. IB. Solar Activity Forecast: Solar activity is expected to be at very low to low levels for the next three days (15-17 March). C-flares are likely from Region 1054. IIA. Geophysical Activity Summary 13/2100Z to 14/2100Z: The geomagnetic field has been at mostly quiet levels for the past 24 hours. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels during the period. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels for the next two days (15-16 March) due to a recurrent coronal hole high-speed stream and a solar sector boundary crossing. Geomagnetic activity is expected to decrease to quiet levels on day three (17 March). III. Event Probabilities 15 Mar-17 Mar Class M 05/05/05 Class X 01/01/01 Proton 01/01/01 PCAF green IV.
