:Product: 1108RSGA.txt :Issued: 2024 Nov 08 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 313 Issued at 2200Z on 08 Nov 2024 IA. Analysis of Solar Active Regions and Activity from 07/2100Z to 08/2100Z: 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 08/0301Z from Region 3883 (S06W20). There are currently 7 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 days one, two, and three (09 Nov, 10 Nov, 11 Nov). IIA. Geophysical Activity Summary 07/2100Z to 08/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 660 km/s at 08/0745Z. Total IMF reached 16 nT at 08/1321Z. The maximum southward component of Bz reached -12 nT at 08/1758Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 101 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at unsettled to active levels on day one (09 Nov) and quiet to active levels on days two and three (10 Nov, 11 Nov). Protons have a slight chance of crossing threshold on days one, two, and three (09 Nov, 10 Nov, 11 Nov). III.
