:Product: 1106RSGA.txt :Issued: 2024 Nov 06 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 06 Nov 2024 IA. Analysis of Solar Active Regions and Activity from 05/2100Z to 06/2100Z: Solar activity has been at high levels for the past 24 hours. The largest solar event of the period was a X2 event observed at 06/1340Z from Region 3883 (S06E07). There are currently 8 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 (07 Nov, 08 Nov, 09 Nov). IIA. Geophysical Activity Summary 05/2100Z to 06/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 490 km/s at 06/0119Z. Total IMF reached 9 nT at 05/2102Z. The maximum southward component of Bz reached -6 nT at 05/2316Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 116 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at unsettled to minor storm levels on day one (07 Nov), quiet to active levels on day two (08 Nov) and unsettled to active levels on day three (09 Nov). Protons have a slight chance of crossing threshold on days one, two, and three (07 Nov, 08 Nov, 09 Nov). III.
