Forecast of Solar and Geomagnetic Activity
27 April - 23 May 2026

Solar activity is expected to reach moderate levels
(R1-R2/Minor-Moderate), with a slight chance for high (R3/Strong),
from 27 Apr - 04 May due to the flare potential from multiple active
regions on the solar disk. The remainder of the outlook period is
likely to be at low levels, with a slight chance for M-class
(R1-R2).

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected reach high levels on 12 Apr, 29 Apr - 05 May, 08-14 May,
and 17-21 May due to the anticipated influence from multiple,
recurrent, CH HSS. The remainder of the outlook period is likely to
be at normal to moderate levels.

Geomagnetic field activity is expected to reach G1 (Minor)
geomagnetic storm levels on 07 May and 15-16 May. Active conditions
are likely on 27 Apr, 30 Apr, 08 May, 17-18 May, and 23 May.
Unsettled conditions are likely on 29 Apr, 01 May, 03-04 May, 09
May, and 21-22 May. All enhancement in geomagnetic activity are due
to the anticipated influence of multiple, recurrent, CH HSSs. The
remainder of the outlook period is expected to be at mostly quiet
levels.
