Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 326 Issued at 2200Z on 22 Nov 2025

IA.  Analysis of Solar Active Regions and Activity from 21/2100Z to
22/2100Z: Solar activity has been at low 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 slight chance for an M-class flare on days one, two, and three (23
Nov, 24 Nov, 25 Nov).

IIA.  Geophysical Activity Summary 21/2100Z to 22/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 483 km/s at 21/2140Z. Total IMF reached 8
nT at 22/2042Z. The maximum southward component of Bz reached -5 nT at
21/2330Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 428 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (23 Nov, 24 Nov, 25
Nov).
