## 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 2026-01-23T13:00Z.
The elevated energetic electron flux levels observed since 2026-01-21T09:30Z (see notification 20260121-AL-004) are caused by the arrival of CME with ID 2026-01-18T18:09:00-CME-001 (see notifications 20260118-AL-005, 20260119-AL-001, 20260119-AL-004, and 20260119-AL-005).
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: 2026-01-21T09:30:00-RBE-001.
## Notes:
The arrival of this CME was associated with a severe geomagnetic storm with ID 2026-01-19T18:00:00-GST-001 (see notifications 20260119-AL-007, 20260120-AL-001, 20260120-AL-002, and 20260121-AL-001). Simulations also indicated that the magnetopause separating magnetospheric and solar wind plasma was close to the geosynchronous orbit starting at 2026-01-19T22:49Z (see notification 20260119-AL-008).
Message Body: *** This SEP event notification was triggered by a long data gap in STEREO A Beacon data from 2026-01-21T16:25Z to 2026-01-22T02:57Z. Once Beacon data returned, the 13-100 MeV proton flux was still above threshold which triggered an automatic notification with ID 20260122-AL-002 (see below).***

## Summary:
Solar energetic particle event detected by STEREO A. The flux of 13-100 MeV protons exceeds 10^(-1) pfu/MeV starting at 2026-01-23T03:05Z.
Message Body: *** From 2026-01-22T05:05Z to 2026-01-22T05:45Z, the GOES >10 MeV integral proton flux threshold exceeded 10 pfu as the original SEP event starting at 2026-01-18T22:55Z was declining below threshold. These points are not considered a separate SEP event as there was no additional flare or CME activity associated with this minor enhancement. The following automatic notification with ID 20260122-AL-002 was triggered (see below).***
