Forecast of Solar and Geomagnetic Activity
20 April - 16 May 2026

Solar activity is expected to be at low levels, with a varying
chance for M-class (R1-R2/Minor-Moderate) flares and a slight chance
for X-class (R3/Strong or greater) flares through 16 May.

No proton events are expected at geosynchronous orbit, barring any
significant, non-recurrent solar activity.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to reach high levels on 20-22 Apr, 27-28 Apr, 30 Apr-05 May
and 08-14 May. Normal to moderate electron flux levels are expected
on 23-26 Apr, 29 Apr, 06-07 May and 15-16 May.

Geomagnetic field activity is expected to remain at quiet to active
levels during most of the outlook period, with the exception of 5
days when G1 (Minor) storm levels are anticipated due to the
recurrent influence of CH HSS: 29-30 Apr (-CH HSS), 07 May (+CH HSS)
and 15-16 May (-CH HSS).
