MOSWOC high energy electron forecast for geostationary orbit
Forecaster summary - Issued 2026-04-26T00:29:29
GOES19 High energy (>2 MeV) electron flux is at background, and is expected to remain somewhat suppressed given oncoming coronal hole influence and the potential glancing CME impacts into Day 1 (26 Apr). Background levels look likely through Day 1 (26 Apr), with flux levels then perhaps increasing back to Moderate to diurnally High levels through Days 2 and 3 (27-28 Apr).
The 24 hour fluence has reduced to background, and is expected to stay at this level through the period. This is supported by MOWSOC REFM and the 27-day Recurrence, which are providing reasonably good guidance, though confidence reduces by the end of the period.
