:Product: 1113RSGA.txt :Issued: 2024 Nov 13 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 318 Issued at 2200Z on 13 Nov 2024 IA. Analysis of Solar Active Regions and Activity from 12/2100Z to 13/2100Z: 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 13/1708Z from Region 3889 (S10W15). There are currently 7 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is likely to be moderate with a slight chance for an X-class flare on days one, two, and three (14 Nov, 15 Nov, 16 Nov). IIA. Geophysical Activity Summary 12/2100Z to 13/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 372 km/s at 13/1212Z. Total IMF reached 9 nT at 13/1223Z. The maximum southward component of Bz reached -8 nT at 13/1113Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 616 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on days one and two (14 Nov, 15 Nov) and quiet to unsettled levels on day three (16 Nov). Protons have a slight chance of crossing threshold on days one, two, and three (14 Nov, 15 Nov, 16 Nov). III.
