Highlights of Solar and Geomagnetic Activity
05 - 11 January 2026
Solar activity ranged from low to moderate levels. Forty-five weak
to middle level C-class activity was observed from various regions
on the disk during the period. A majority of the activity was
observed from Regions 4334 (S16, L=200, class/area Dao/150 on 08
Jan), 4336 (S10, L=166, class/area Eko/430 on 09 Jan) and 4337 (N25,
L=243, class/area Dao/020 on 08 Jan). At 11/2314 UTC, a
long-duration M3.3 (R1-Minor) flare was observed from behind the ESE
limb. Several potential Earth-directed CMEs were observed leaving
the Sun on 08 Jan with possible impact on late 10 Jan to early on 11
Jan.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at
normal to moderate levels on 05, 08, 09 and 11 Jan with high levels
observed on 06, 07 and 10 Jan. A peak flux of 2,507 pfu was observed
on 10/1635 UTC.
Geomagnetic field activity was at quiet to active levels on 05 Jan
in response to declining CH HSS influence. Quiet levels were
observed on 06 and 07 Jan. Quiet to active levels were observed on
08, 09 and early 10 Jan due to CH HSS influence. Activity levels
increased to G1 (Minor) to G2 (Moderate) activity levels during late
10 Jan through 11 Jan due to CME effects from the 08 Jan CME coupled
with CH HSS effects.
Forecast of Solar and Geomagnetic Activity
12 January - 07 February 2026
Solar activity is likely to remain at low levels, with a chance for
R1 (Minor) conditions and a slight chance for R2/R3
(Moderate/Strong) over the next forecast period due to multiple
regions on the visible disk as well as regions expected to return.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is
expected to reach high levels on 12, 14-15, 21-27 and 30-31 Jan and
01-03 and 05-07 Feb due to the anticipated influence of multiple,
recurrent coronal holes. The remainder of the outlook period is
likely to be at normal to moderate levels.
Geomagnetic field activity is likely to reach G1 (Minor) geomagnetic
storm levels on 12 and 29 Jan; unsettled to active levels on 13-16,
19-23, 27-28, 30-31 Jan and 04-07 Feb. All enhancements in
geomagnetic activity are due to the anticipated influence of
multiple, recurrent CH HSSs. The remainder of the outlook period is
expected to mostly quiet.
