:Product: 0107RSGA.txt :Issued: 2026 Jan 07 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 7 Issued at 2200Z on 07 Jan 2026 IA. Analysis of Solar Active Regions and Activity from 06/2100Z to 07/2100Z: Solar activity has been at low levels for the past 24 hours. 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 and a slight chance for an X-class flare on days one, two, and three (08 Jan, 09 Jan, 10 Jan). IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 378 km/s at 07/1405Z. Total IMF reached 9 nT at 07/1318Z. The maximum southward component of Bz reached -6 nT at 07/2100Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1260 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on day one (08 Jan), quiet to minor storm levels on day two (09 Jan) and quiet to active levels on day three (10 Jan). Protons have a slight chance of crossing threshold on days one, two, and three (08 Jan, 09 Jan, 10 Jan). III.
