## Summary:
Significantly elevated energetic electron fluxes in the Earth's outer radiation belt. GOES "greater than 2.0 MeV" integral electron flux is above 1000 pfu starting at 2026-03-08T14:55Z.
The elevated energetic electron flux levels are caused by a coronal hole high speed stream starting on 2026-03-06, reaching maximum sustained speeds of approximately 650 km/s. The solar wind speed observed at L1 is currently around 498 km/s.
NASA spacecraft at GEO, MEO and other orbits passing through or in the vicinity of the Earth's outer radiation belt can be impacted.
