:Product: 0107RSGA.txt :Issued: 2016 Jan 07 2245 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 7 Issued at 2200Z on 07 Jan 2016 IA. Analysis of Solar Active Regions and Activity from 06/2100Z to 07/2100Z: Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C1 event observed at 07/0617Z from Region 2480 (N03E58). There are currently 4 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be very low with a chance for a C-class flares and a slight chance for an M-class flare on days one, two, and three (08 Jan, 09 Jan, 10 Jan). IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed, as measured by the ACE spacecraft, reached a peak speed of 632 km/s at 06/2251Z. Total IMF reached 8 nT at 06/2333Z. The maximum southward component of Bz reached -6 nT at 07/0056Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 5126 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on day one (08 Jan) and quiet levels on days two and three (09 Jan, 10 Jan). III.
