Highlights of Solar and Geomagnetic Activity
29 December - 04 January 2026

Solar activity ranged from low to high levels. High levels were
observed on 31 Dec following an M7.1/1N flare at 31/1351 UTC from
Region 4324 (N25, L=288, class/area=Dao/230 on 29 Dec). Associated
with the event was Type IV and Type II radio sweep, a Tenflare, and
a CME signature to the NE in subsequent coronagraph imagery.
Modeling of the CME event suggested passage by Earth late on 03 Jan.
Moderate levels were observed on 01 Jan following an M1/Sf flare at
29/0651 from Region 4325 (S08, L=296, class/area=Eki/330 on 01 Jan).
The other 21 numbered active regions across the visible disk this
week were either quiet or only produced C-class activity. A Type II
radio sweep was reported on 02 Jan but was associated with a CME
that erupted from beyond the W limb.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels over the past seven days.

Geomagnetic field activity was at mostly quiet to unsettled levels
on everyday but 02 Jan. G1 (Minor) geomagnetic storm levels were
observed on late on 02 Jan following the arrival of the last of a
set of weak CMEs that left the Sun over 28-31 Dec. Total magnetic
field strength reached a peak of 09 nT as the CME passed. Bz reached
as far south as -8 nT. Solar wind speeds peaked between ~600-700
km/s. While influence from a negative polarity coronal hole was
observed beginning on 31 Dec, no significant geomagnetic activity
was observed from the feature over the following days.

Forecast of Solar and Geomagnetic Activity
05 January - 31 January 2026

Solar activity is likely to remain at low levels, with a chance for
moderate (R1-Minor) conditions and a slight chance for high (R2/R3-Moderate-Strong) over the next solar rotation due to multiple
regions on the visible disk as well as regions expected to return
from the Sun's farside.

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 05 Jan and 15 Jan - 13 Jan due to
the anticipated influence of multiple, recurrent coronal holes. The
remainder of the outlook period is likely to at normal to moderate
levels.

Geomagnetic field activity is likely to reach G1 (Minor) geomagnetic
storm levels on 13-14 Jan, 17-20 Jan, and 29 Jan; active levels are
likely on 05 Jan and 28 Jan; unsettled levels are likely on 09-10
Jan, 12 Jan, 21-22 Jan, 27 Jan, and 30-31 Jan. All enhancements in
geomagnetic activity are due to the anticipated influence of
multiple, recurrent, coronal holes. The remainder of the outlook
period is expected to be mostly quiet.
