:Product: 0301RSGA.txt :Issued: 2024 Mar 01 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 61 Issued at 2200Z on 01 Mar 2024 IA. Analysis of Solar Active Regions and Activity from 29/2100Z to 01/2100Z: Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C3 event observed at 01/0125Z from Region 3590 (N18W80). 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 and a slight chance for an X-class flare on day one (02 Mar) and expected to be low with a chance for M-class flares on days two and three (03 Mar, 04 Mar). IIA. Geophysical Activity Summary 29/2100Z to 01/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 427 km/s at 01/0342Z. Total IMF reached 5 nT at 01/0323Z. The maximum southward component of Bz reached -4 nT at 01/0206Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 138 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on days one and two (02 Mar, 03 Mar) and quiet to unsettled levels on day three (04 Mar). Protons greater than 10 Mev have a slight chance of crossing threshold on day one (02 Mar). III. Event probabilities 02 Mar-04 Mar Class M 50/25/25 Class X 10/01/01 Proton 15/01/01 PCAF green IV.
