:Product: 0305RSGA.txt :Issued: 2013 Mar 05 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 Solar Geophysical Activity Report and Forecast SDF Number 64 Issued at 2200Z on 05 Mar 2013 IA. Analysis of Solar Active Regions and Activity from 04/2100Z to 05/2100Z: Solar activity has been at moderate levels for the past 24 hours. The largest solar event of the period was a M1 event observed at 05/0754Z from Region 1686 (S14W59). There are currently 7 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be low with a chance for M-class flares on days one and two (06 Mar, 07 Mar) and expected to be very low with a chance for a C-class flares and a slight chance for an M-class flare on day three (08 Mar). IIA. Geophysical Activity Summary 04/2100Z to 05/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed, as measured by the ACE spacecraft, reached a peak speed of 437 km/s at 05/0131Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 7332 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on days one and two (06 Mar, 07 Mar) and quiet levels on day three (08 Mar). III.
