Forecast of Solar and Geomagnetic Activity
13 October - 08 November 2025

Solar activity is expected to be at low levels throughout the period
with a varying chance for M-flare (R1-R2/Minor-Moderate) activity.

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 13-19, 21-24, and 28 Oct-08 Nov.
Normal to moderate levels are expected throughout the remainder of
the period.

Geomagnetic field activity is expected to reach active and G1
(Minor) storm levels on 13 Oct, and quiet to unsettled levels on 14
Oct, in response to waning negative polarity CH HSS influences.
Periods of active conditions are likely on 15 Oct due to the
anticipated arrival of a CME from 11 Oct, and again on 16 Oct due to
the anticipated arrival of a CME from 12 Oct. Periods of G1 (Minor)
storm levels are likely on 20 Oct due to negative polarity CH HSS
influences. Active conditions are likely over 25-26 Oct in response
to negative polarity CH HSS influences. Periods of G1 storming are
likely on 28 and 30 Oct, with periods of G2 (Moderate) storming
likely on 29 Oct, due to positive polarity CH HSS influences. G1
(Minor) storms are likely again on 08 Nov due to the anticipated
influences of another recurrent, negative polarity CH HSS. Quiet and
quiet to unsettled levels are expected to prevail throughout the
remainder of the period.
