:Product: Report of Solar-Geophysical Activity :Issued: 2025 Jul 08 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 189 Issued at 2200Z on 08 Jul 2025 IA. Analysis of Solar Active Regions and Activity from 07/2100Z to 08/2100Z: 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 expected to be low with a chance for M-class flares on days one, two, and three (09 Jul, 10 Jul, 11 Jul). IIA. Geophysical Activity Summary 07/2100Z to 08/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 611 km/s at 07/2313Z. Total IMF reached 9 nT at 07/2124Z. The maximum southward component of Bz reached -7 nT at 08/0428Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 393 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one, two, and three (09 Jul, 10 Jul, 11 Jul). III.
