:Product: 0902RSGA.txt :Issued: 2014 Sep 02 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 245 Issued at 2200Z on 02 Sep 2014 IA. Analysis of Solar Active Regions and Activity from 01/2100Z to 02/2100Z: Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C3 event observed at 02/1315Z from Region 2152 (S16W12). There are currently 6 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, two, and three (03 Sep, 04 Sep, 05 Sep). IIA. Geophysical Activity Summary 01/2100Z to 02/2100Z: 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 521 km/s at 02/0825Z. Total IMF reached 6 nT at 02/1646Z. The maximum southward component of Bz reached -5 nT at 02/0439Z. Protons greater than 10 MeV at geosynchronous orbit reached a peak level of 2 pfu at 02/2040Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 6112 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on days one, two, and three (03 Sep, 04 Sep, 05 Sep). III.
