:Product: 0405RSGA.txt :Issued: 2026 Apr 05 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 95 Issued at 2200Z on 05 Apr 2026 IA. Analysis of Solar Active Regions and Activity from 04/2100Z to 05/2100Z: Solar activity has been at moderate levels for the past 24 hours. There are currently 7 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 (06 Apr, 07 Apr, 08 Apr). IIA. Geophysical Activity Summary 04/2100Z to 05/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 622 km/s at 05/0646Z. Total IMF reached 5 nT at 05/0733Z. The maximum southward component of Bz reached -4 nT at 05/0714Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 5995 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on days one and two (06 Apr, 07 Apr) and quiet levels on day three (08 Apr). Protons have a slight chance of crossing threshold on days one, two, and three (06 Apr, 07 Apr, 08 Apr). III.
