:Product: 0203RSGA.txt :Issued: 2024 Feb 03 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 34 Issued at 2200Z on 03 Feb 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 C7 event observed at 03/0554Z. There are currently 8 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is likely to be moderate with a slight chance for an X-class flare on days one, two, and three (04 Feb, 05 Feb, 06 Feb). IIA. Geophysical Activity Summary 02/2100Z to 03/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 346 km/s at 03/1626Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 274 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (04 Feb), quiet to minor storm levels on day two (05 Feb) and quiet to unsettled levels on day three (06 Feb). Protons have a slight chance of crossing threshold on days one, two, and three (04 Feb, 05 Feb, 06 Feb). III.
