:Product: 0304RSGA.txt :Issued: 2024 Mar 04 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 64 Issued at 2200Z on 04 Mar 2024 IA. Analysis of Solar Active Regions and Activity from 03/2100Z to 04/2100Z: Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C2 event observed at 04/0316Z from Region 3602 (N19E29). There are currently 9 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 day one (05 Mar) and expected to be low with a slight chance for an M-class flare on days two and three (06 Mar, 07 Mar). IIA. Geophysical Activity Summary 03/2100Z to 04/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 591 km/s at 04/0613Z. Total IMF reached 16 nT at 03/2306Z. The maximum southward component of Bz reached -13 nT at 03/2206Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 129 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one, two, and three (05 Mar, 06 Mar, 07 Mar). III.
