Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 10 Issued at 2200Z on 10 Jan 2026IA. Analysis of Solar Active Regions and Activity from 09-2100Z to 10-2100Z Solar activity has been at low levels for the past 24 hours.
There are currently 4 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is likely to be low with a
slight chance for an M-class flare on days one, two, and three (11 Jan,
12 Jan, 13 Jan).
IIA. Geophysical Activity Summary 09-2100Z to 10-2100Z

orbit reached a peak level of 2507 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at unsettled to minor storm levels on day one (11 Jan) and quiet
to active levels on days two and three (12 Jan, 13 Jan).
