Highlights of Solar and Geomagnetic Activity
06 - 12 October 2025

Solar activity reached moderate levels on 09 Oct when Region 4236
(N10, L=62, class/area=Ekc/320 on 04 Oct) produced an M2.0 flare
(R1-Minor) at 09/1231 UTC; the largest event and sole M-flare of the
period. Solar activity was at low levels throughout the remainder of
the period. Region 4246 (N24, L= 290, class/area=Dai/180 on 12 Oct)
produced several C-flares over 10-12 Oct, along with two
Earth-directed CMEs. The first CME was associated with coronal
dimming near AR4246 at around 11/0115 UTC, and the second CME was
associated with a long-duration C9.6/1f flare at 12/1350 UTC from
AR4246. The first CME is anticipated to arrive on 15 Oct, and the
second CME is anticipated to arrive on 16 Oct.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels on 06-12 Oct.

Geomagnetic field activity was quiet on 06 Oct. Periods of active
conditions were observed on 07-08 Oct due to the passage of CMEs
that left the Sun on 03 Oct. Quiet conditions were observed again on
09 Oct. Active conditions were observed on 10 Oct, with periods of
G1 (Minor) storming observed on 11-12 Oct, due to negative polarity
CH HSS influences and possible embedded transient influences.
