:Product: 1029RSGA.txt :Issued: 2024 Oct 29 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 303 Issued at 2200Z on 29 Oct 2024 IA. Analysis of Solar Active Regions and Activity from 28/2100Z to 29/2100Z: 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 29/1633Z from Region 3873 (S08W36). There are currently 12 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 (30 Oct, 31 Oct, 01 Nov). IIA. Geophysical Activity Summary 28/2100Z to 29/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 555 km/s at 29/0119Z. Total IMF reached 7 nT at 28/2250Z. The maximum southward component of Bz reached -7 nT at 29/1812Z. Protons greater than 10 MeV at geosynchronous orbit reached a peak level of 240 pfu at 28/2235Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 190 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (30 Oct), quiet levels on day two (31 Oct) and quiet to unsettled levels on day three (01 Nov). Protons are expected to cross threshold on day one (30 Oct), are expected to cross threshold on day two (31 Oct) and have a chance of crossing threshold on day three (01 Nov). III.
