:Product: onRSGA.txt :Issued: 2024 Dec 03 2325 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 337 Issued at 2322Z (AMD) on 03 Dec 2024 IA. Analysis of Solar Active Regions and Activity from 02/2100Z to 03/2100Z: Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C6 event observed at 03/0544Z. There are currently 7 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be low with a chance for M-class flares on days one, two, and three (04 Dec, 05 Dec, 06 Dec). IIA. Geophysical Activity Summary 02/2100Z to 03/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 460 km/s at 03/1851Z. Total IMF reached 14 nT at 03/0047Z. The maximum southward component of Bz reached -8 nT at 03/1711Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 103 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one, two, and three (04 Dec, 05 Dec, 06 Dec). III.
