Forecast of Solar and Geomagnetic Activity
25 August - 20 September 2025

Solar activity is expected to be at low levels, with varying chances
for M-class flares (R1-R2/Minor-Moderate events) through 20 Sep.

The greater than 10 MeV proton levels are expected to be at or above
10 pfu levels on 25 Aug before dropping below the 10 pfu level by 26
Aug. Levels should remain below thresholds through 20 Sep, with no
additional events expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at moderate levels on 25-26 Aug, 29 Aug-5 Sep, and
15-19 Sep. Conditions are likely to see high levels on 27-28 Aug,
6-14 Sep, and again on 20 Sep.

Geomagnetic field activity is expected to be at mostly quiet levels
on 29 Aug-3 Sep and again on 11-14 Sep. Unsettled levels are likely
on 25-28 Aug, 7-10 Sep, and 17-20 Sep. Active conditions are likely
on 4-9 Sep and 15-16 Sep, with possible minor storming on 4-6 Sep
and 15 Sep. All increased activity levels are associated with
coronal hole high speed stream influence.
