Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 54 Issued at 2200Z on 23 Feb 2026IA. Analysis of Solar Active Regions and Activity from 22-2100Z to 23-2100Z Solar activity has been at very low levels for the past 24
hours. There are currently 0 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be very low
with a chance for a C-class flares and a slight chance for an M-class
flare on days one, two, and three (24 Feb, 25 Feb, 26 Feb).
IIA. Geophysical Activity Summary 22-2100Z to 23-2100Z

Solar wind speed reached a peak of 768 km/s at 23/0255Z. Total IMF
reached 7 nT at 23/0151Z. The maximum southward component of Bz reached
-6 nT at 23/0219Z. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 4,958 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at unsettled to active levels on days one, two, and three (24 Feb,
25 Feb, 26 Feb).
