Forecast of Solar and Geomagnetic Activity
03 November - 29 November 2025

Solar activity is expected to be at moderate levels on 03-17 Nov due
to the delayed return of Regions 4246 and 4248, that seem to be
rotating into the Earthside solar disk between 03-04 Nov. At least
two other regions are expected to emerge from the East limb until 10
Nov, as observed at GONG farside images. Solar activity could remain
at moderate levels through 29 Nov if these regions have significant
magnetic complexity.

No proton events are expected at geosynchronous orbit. However, if
the upcoming returning Regions 4246 and 4248 continue to be
magnetically complex with enhanced activity, an isolated proton
event is possible between 07-12 Nov.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to remain at high levels until 13 Nov, due to the
persistent perturbations at Earth's magnetosphere associated to
the CH HSS. Moderate levels are expected on 14-26 Nov period, and
high levels are expected to return on 27 Nov.

Geomagnetic field activity is expected to be mostly quiet to active
during the 27-day period, with minor storming (G1) levels likely on
07-08, 15 and 26-27 Nov due to recurrence of CH HSS influences.
