:Product: 1202RSGA.txt :Issued: 2020 Dec 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 337 Issued at 2200Z on 02 Dec 2020 IA. Analysis of Solar Active Regions and Activity from 01/2100Z to 02/2100Z: Solar activity has been at very low levels for the past 24 hours. The largest solar event of the period was a C1 event observed at 01/2320Z from Region 2786 (S17W27). 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 (03 Dec, 04 Dec, 05 Dec). IIA. Geophysical Activity Summary 01/2100Z to 02/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 454 km/s at 01/0313Z. Total IMF reached 7 nT at 02/1613Z. The maximum southward component of Bz reached -3 nT at 01/2102Z. Protons greater than 10 MeV at geosynchronous orbit reached a peak level of 5 pfu at 02/0620Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1529 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one, two, and three (03 Dec, 04 Dec, 05 Dec). III.
