:Product: 1103RSGA.txt :Issued: 2024 Nov 03 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 308 Issued at 2200Z on 03 Nov 2024 IA. Analysis of Solar Active Regions and Activity from 02/2100Z to 03/2100Z: 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 03/1524Z from Region 3869 (S18W74). There are currently 13 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be moderate with a chance for X-class flares on day one (04 Nov) and likely to be moderate with a slight chance for an X-class flare on day two (05 Nov) and expected to be low with a chance for M-class flares and a slight chance for an X-class flare on day three (06 Nov). IIA. Geophysical Activity Summary 02/2100Z to 03/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 533 km/s at 02/2345Z. Total IMF reached 11 nT at 03/0432Z. The maximum southward component of Bz reached -8 nT at 02/2132Z. Protons greater than 10 MeV at geosynchronous orbit reached a peak level of 2 pfu at 02/2305Z. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (04 Nov), quiet to unsettled levels on day two (05 Nov) and quiet levels on day three (06 Nov). Protons greater than 10 Mev have a slight chance of crossing threshold on day one (04 Nov) and have a slight chance of crossing threshold on day two (05 Nov). III.
