Forecast of Solar and Geomagnetic Activity
10 August - 05 September 2026

Solar activity is expected to range from very low to low levels
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 12-16 and 22-23 Aug. Normal to
moderate levels are expected to prevail throughout the remainder of
the period.

Geomagnetic field activity is likely to reach G1 (Minor) storm
levels on 11 Aug due to the anticipated arrival of a CME that left
the Sun on 08 Aug, and again on 19 Aug due to recurrent CH HSS
influences. Active conditions are likely on 10 and 17-18 Aug, while
quiet and quiet to unsettled conditions are likely to prevail
throughout the remainder of the outlook period.
