Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 44 Issued at 2200Z on 13 Feb 2026IA. Analysis of Solar Active Regions and Activity from 12-2100Z to 13-2100Z Solar activity has been at moderate levels for the past 24
hours. There are currently 4 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 (14
Feb, 15 Feb, 16 Feb).
IIA. Geophysical Activity Summary 12-2100Z to 13-2100Z

The geomagnetic field is expected
to be at quiet to active levels on day one (14 Feb), unsettled to minor
storm levels on day two (15 Feb) and quiet to minor storm levels on day
three (16 Feb).
