Solar activity report
Report of Solar-Geophysical Activity 2026 Jan 06 2200 UTCPrepared by the NOAA © SWPC and processed by SpaceWeatherLive.com
Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 6 Issued at 2200Z on 06 Jan 2026IA. Analysis of Solar Active Regions and Activity from 05-2100Z to 06-2100Z 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 chance for M-class flares and a slight chance for an X-class flare on
days one, two, and three (07 Jan, 08 Jan, 09 Jan).
IIA. Geophysical Activity Summary 05-2100Z to 06-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 424 km/s at 05/2118Z. Total IMF reached 7 nT at
05/2249Z. The maximum southward component of Bz reached -5 nT at
06/0257Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 1326 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet levels on days one and two (07 Jan, 08 Jan) and quiet to
minor storm levels on day three (09 Jan). Protons have a slight chance
of crossing threshold on days one, two, and three (07 Jan, 08 Jan, 09
Jan).
