:Product: 1119RSGA.txt :Issued: 2024 Nov 19 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 324 Issued at 2200Z on 19 Nov 2024 IA. Analysis of Solar Active Regions and Activity from 18/2100Z to 19/2100Z: 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 19/0000Z from Region 3889 (S09W95). There are currently 8 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be low with a chance for M-class flares and a slight chance for an X-class flare on days one, two, and three (20 Nov, 21 Nov, 22 Nov). IIA. Geophysical Activity Summary 18/2100Z to 19/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 433 km/s at 19/1617Z. Total IMF reached 10 nT at 19/1706Z. The maximum southward component of Bz reached -8 nT at 19/1044Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 745 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one, two, and three (20 Nov, 21 Nov, 22 Nov). III.
