Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 190 Issued at 2200Z on 09 Jul 2025

IA.  Analysis of Solar Active Regions and Activity from 08/2100Z to
09/2100Z: Solar activity has been at moderate levels for the past 24
hours. There are currently 6 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 (10 Jul, 11 Jul,
12 Jul).

IIA.  Geophysical Activity Summary 08/2100Z to 09/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 555 km/s at 08/2133Z. Total IMF reached 8
nT at 08/2115Z. The maximum southward component of Bz reached -4 nT at
09/0109Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 1211 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (10 Jul, 11 Jul) and quiet to
unsettled levels on day three (12 Jul).
