Highlights of Solar and Geomagnetic Activity
24 - 30 November 2025

Solar activity was at low levels over 24-27 and 30 Nov with C-class
flare activity observed. High levels of solar activity were observed
on 28 Nov when Region 4294 (S15, L=293, class/area=Fkc/1100 on 30
Nov) produced an impulsive M5.9 flare (R2-Moderate) at 28/2222 UTC,
with Type-II (828 km/s) and Tenflare (240 sfu) radio emissions, as
the region rotated onto the disk from the SE limb. Solar activity
reached high levels again on 29 Nov with six M-class flares
(R1-Minor) observed from Region 4294. No Earth-directed CMEs were
detected during the summary period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was a
normal to moderate levels on 24-27 Nov, with high levels observed on
28-30 Nov.

Geomagnetic field activity reached active levels on 24 Nov, and G1
(Minor) storm levels on 25 Nov, due to negative polarity CH HSS
influences. Active levels were observed again on 26 Nov as negative
polarity CH HSS influences subsided, followed by the onset of
positive polarity CH HSS influences. Periods of G1 (Minor) storming
were observed on 27 Nov, with periods of active conditions observed
over 28-30 Nov, due to continued positive polarity CH HSS
influences.
