## 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 2026-03-15T16:05Z.
The elevated energetic electron flux levels are caused by a coronal hole high speed stream starting on 2026-03-13, reaching maximum sustained speeds of approximately 700 km/s. The solar wind speed observed at L1 is currently around 615 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.
Activity ID: 2026-03-15T16:05:00-RBE-001.
## Notes:
This coronal hole high speed stream is also associated with geomagnetic storm with ID 2026-03-13T21:00:00-GST-001.

## Summary:
Significantly elevated energetic electron fluxes in the Earth's outer radiation belt. GOES "greater than 2.0 MeV" integral electron flux remains elevated, recently crossing the threshold of 1000 pfu at 2026-03-12T12:25Z.
The elevated energetic electron flux levels observed since 2026-03-08T14:55Z are caused by a coronal hole high speed stream starting on 2026-03-06 (see notifications 20260308-AL-001, 20260308-AL-002, 20260310-AL-001).
NASA spacecraft at GEO, MEO and other orbits passing through or in the vicinity of the Earth's outer radiation belt can be impacted.
