:Product: 1107RSGA.txt :Issued: 2025 Nov 07 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 311 Issued at 2200Z on 07 Nov 2025 IA. Analysis of Solar Active Regions and Activity from 06/2100Z to 07/2100Z: Solar activity has been at moderate levels for the past 24 hours. 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 (08 Nov, 09 Nov, 10 Nov). IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z: The geomagnetic field has been at unsettled to minor storm levels for the past 24 hours. Solar wind speed reached a peak of 859 km/s at 07/1028Z. Total IMF reached 17 nT at 07/0614Z. The maximum southward component of Bz reached -16 nT at 07/0539Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 340 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at active to major storm levels on day one (08 Nov), quiet to minor storm levels on day two (09 Nov) and unsettled to major storm levels on day three (10 Nov). Protons have a slight chance of crossing threshold on days one, two, and three (08 Nov, 09 Nov, 10 Nov). III.
