## Summary:
Significantly elevated energetic electron fluxes in the Earth's outer radiation belt. GOES "greater than 2.0 MeV" integral electron flux first crossed the threshold of 1000 pfu starting at 2025-09-12T16:40Z (see notifications 20250912-AL-002 and 20250912-AL-003). The most recent crossing of the 1000 pfu threshold was at 2025-09-14T15:10Z and the fluxes are currently elevated but below the threshold.
The elevated energetic electron flux levels are caused by the arrival of a coronal hole high speed stream starting on 2025-09-04, reaching a maximum speed of approximately 600 km/s, and the arrival of the CME with ID 2025-09-04T20:30:00-CME-001 (see notifications 20250905-AL-001 and 20250906-AL-001). This CME arrival was detected at L1 by ACE at 2025-09-06T13:51Z (see notification 20250906-AL-002). The solar wind speed observed at L1 is currently around 380 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: 2025-09-12T16:40:00-RBE-001.
## Notes:
Energetic electron flux levels were previously elevated starting at 2025-09-09T14:15Z (see notifications 20250909-AL-001 and 20250909-AL-002) due to the same arrival of the coronal hole high speed stream starting on 2025-09-04 and CME with ID 2025-09-04T20:30:00-CME-001 (see notifications 20250905-AL-001, 20250906-AL-001).
This coronal hole high speed stream is also associated with geomagnetic storm
with ID 2025-09-09T21:00:00-GST-001 (see notifications 20250910-AL-001 and 20250910-AL-002).
