## Summary:
Significantly elevated energetic electron fluxes in the Earth's outer radiation belt. GOES "greater than 2.0 MeV" integral electron flux remains elevated, most recently crossing the threshold of 1000 pfu at 2026-01-28T23:35Z.
The currently observed elevated energetic electron flux levels are caused by the coronal hole high speed stream starting on 2026-01-28, reaching a maximum speed of approximately 750 km/s, has further enhanced the electron fluxes. The solar wind speed observed at L1 is currently around 430 km/s.
The arrival of the 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) had previously enhanced the electron fluxes starting at 2026-01-21T09:30Z (see notifications 20260121-AL-004, 20260123-AL-002, 20260125-AL-001, 20260127-AL-001 and 20260129-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.

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 2026-01-28T23:35Z.
The elevated energetic electron flux levels observed since 2026-01-21T09:30Z (see notifications 20260121-AL-004, 20260123-AL-002, 20260125-AL-001 and 20260127-AL-001) are caused by the arrival of the 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).

## 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). Additionally, simulations 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).
