MOSWOC high energy electron forecast for geostationary orbit
Forecaster summary - Issued 2025-12-17T00:49:34
Electron Flux is expected to be background to Moderate at first, with an increasing risk of reaching High levels during the diurnal maxima as the High Speed Stream of CH08/- wanes in coming days and electrons relax back into their usual orbits within the Van Allen belts.
Associated Electron Fluence levels are expected to rise in coming days, with a Chance of reaching Active later in the forecast period. MOSWOC REFM output supports a gradually increasing fluence trend, with peak fluence levels reaching Active by day 3 (19 Dec).
