Forecast of Solar and Geomagnetic Activity
26 October - 21 November 2026

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

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 26-30 Oct, and 03-05 Nov, and 19-21
Nov. Normal to moderate flux levels are expected for the remainder
or the outlook period.

Due to multiple recurrent CH HSSs, geomagnetic field activity is
likely to reach G1 (Minor) storm levels on 31 Oct, with active
levels likely on 01, 09, and 17-18 Nov. The remainder of the outlook
period is expected to be at quiet or quiet to unsettled levels.
