Forecaster summary - Issued 2025-05-29T00:23:12

Current electron flux is varying between moderate and background levels and likely to remain similar at first. Charging of the Van Allen belts is expected once connection is made to CH52/- but may be diminished by any geomagnetic activity initially. Significantly increased levels of electron flux at GEO is not forecast until day 2 (30 May) or day 3 (31 May) when the Van Allen belts relax back out, with persistently High levels expected.

Electron fluence is currently below the Active (1e8 integrated pfu) threshold, on a relatively steady trend. Based on persistence forecasting (from MOSWOC REFM) Active levels of fluence are possible late on day 2 (30 May) and then expected on day 3 and day 4 (31 May and 1 June).
