Forecaster summary - Issued 2025-07-31T00:14:19

High energy electron flux at GEO is expected to be Background to Moderate. There is a chance that the Electron flux will increase slightly through the period as the Van Allen belt relaxes and expands back towards GEO after any enhancement from the high speed stream/s of CH67/-, with High levels likely to be brief, and only occurring at diurnal maximum.

The corresponding electron fluence is on a flat trend well below the Active (1e8 integrated flux) threshold. There is a rising slight chance of becoming Active through the period .

MOSWOC REFM output looks to be providing good guidance and supports fluence levels staying below Active.
