Forecast of Solar and Geomagnetic Activity
31 August - 26 September 2026

Solar activity is expected to be at very low to low levels, with a
chance for moderate levels and a slight chance for high levels
throughout the forecast period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at high levels on 31 Aug - 06 Sep, then again from
16-23 Sep. Levels are expected to be at normal to moderate levels
from 07 - 15 Sep, and again from 24-26 Sep.

Geomagnetic field activity is expected to decrease from unsettled
levels on 31 Aug to mostly quiet levels from 01-11 Sep and again
from 17-23 Sep. Unsettled to active conditions are expected from
12-16 Sep due to negtive polarity CH HSS influence, then again from
24-26 Sep under positive polarity CH HSS influence.
