:Product: 1012RSGA.txt :Issued: 2016 Oct 12 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 286 Issued at 2200Z on 12 Oct 2016 IA. Analysis of Solar Active Regions and Activity from 11/2100Z to 12/2100Z: 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 12/1155Z from Region 2599 (S14W50). There are currently 3 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 on days one, two, and three (13 Oct, 14 Oct, 15 Oct). IIA. Geophysical Activity Summary 11/2100Z to 12/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 419 km/s at 11/2217Z. Total IMF reached 5 nT at 11/2112Z. The maximum southward component of Bz reached -4 nT at 11/2217Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 767 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to minor storm levels on day one (13 Oct), quiet to major storm levels on day two (14 Oct) and unsettled to active levels on day three (15 Oct).
