Highlights of Solar and Geomagnetic Activity -26 October - 01 November 2026
.JPG)
Solar activity was at low levels with nine C-Class flares observed.
Region 4561 (S11, L=28, class/area=Dai/030 on 26 Oct) produced the
largest event of the period: a C2.8 flare at 26/1840 UTC, as well as
nearly all of the remaining C-class flares of the period. The only
exception was a C1.5 flare at 26/0134 UTC from Region 4560 (N13,
L=49, class/area=Fao/020 on 26 Oct). The only notable CME activity
was from a filament lift-off at approximately 26/2142 UTC from an
area near N30E75. Analysis indicated mostly a miss, though a
glancing blow was not ruled out of the question on 31 Oct.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at
high levels throughout the period, with the exception of 31 Oct when
values dropped to moderate levels.
Geomagnetic field activity was at quiet levels 26-29 Oct, quiet to
active levels on 30 Oct, unsettled to G2 (Moderate) levels on 31
Oct, and quiet to G1 (Minor) levels on 01 Nov. Activity increased
the last two days as a result of the onset of a positive polarity CH
HSS combined with possible CME effects mixed in from the 26 Oct
filament eruption.
Forecast of Solar and Geomagnetic Activity -02 November - 28 November 2026
Solar activity is expected to be predominantly at low levels, with a
slight chance of isolated M-class
(R1-R2/Minor-Moderate) radio blackouts) flare activity associated
with any developing spot groups during the period.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at moderate levels on 02 Nov and 06-18 Nov. Flux
levels are anticipated to reach high levels on 03-05 Nov and 19-28
Nov.
Geomagnetic field activity is expected to be at mostly quiet levels
on 03-04 Nov, 08 Nov, 13-15 Nov, and 20-25 Nov. Unsettled to active
periods are anticipated on 02 Nov, 05-07 Nov, 09-12 Nov, and 26 Nov.
An increase to G1, possibly G2, geomagnetic storm levels is likely on
27-28 Nov. The increase in activity is associated with multiple
recurrent coronal holes.
