:Product: 1105RSGA.txt :Issued: 2024 Nov 05 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 310 Issued at 2200Z on 05 Nov 2024 IA. Analysis of Solar Active Regions and Activity from 04/2100Z to 05/2100Z: Solar activity has been at moderate levels for the past 24 hours. The largest solar event of the period was a M2 event observed at 05/0654Z. 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 (06 Nov, 07 Nov, 08 Nov). IIA. Geophysical Activity Summary 04/2100Z to 05/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 517 km/s at 05/1642Z. Total IMF reached 9 nT at 05/1253Z. The maximum southward component of Bz reached -7 nT at 05/1336Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 124 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (06 Nov), quiet to minor storm levels on day two (07 Nov) and quiet to unsettled levels on day three (08 Nov). Protons have a slight chance of crossing threshold on days one, two, and three (06 Nov, 07 Nov, 08 Nov). III.
