Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 9 Issued at 2200Z on 09 Jan 2026IA. Analysis of Solar Active Regions and Activity from 08-2100Z to 09-2100Z Solar activity has been at low levels for the past 24 hours.
There are currently 5 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 and two (10 Jan, 11 Jan)
and expected to be low with a slight chance for an M-class flare on day
three (12 Jan).
IIA. Geophysical Activity Summary 08-2100Z to 09-2100Z
The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 549 km/s at 09/2011Z. Total IMF reached 16
nT at 09/1117Z. The maximum southward component of Bz reached -10 nT at
08/2309Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 433 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to minor storm levels on day one (10 Jan), unsettled to
minor storm levels on day two (11 Jan) and quiet to active levels on day
three (12 Jan).
