Direction (lon./lat.): 82/-36 in Heliocentric Earth Equatorial coordinates.
Activity ID: 2026-01-17T07:00:00-CME-001
Based on preliminary analysis by the Moon to Mars Space Weather Analysis Office and heliospheric modeling carried out at NASA Community Coordinated Modeling Center, it is estimated that the CME may impact Europa Clipper (minor impact), Juice (glancing blow), and STEREO A (glancing blow).

## Notes:
This CME event (2026-01-17T03:00:00-CME-001) is associated with C4.7 flare from Active Region 14336 (S09W88) with ID 2026-01-17T02:42:00-FLR-001 which peaked at 2026-01-17T02:46Z.

## 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 2026-01-16T12:05Z.
The elevated energetic electron flux levels observed since 2026-01-12T10:05Z (see notifications 20260112-AL-002 and 20260114-AL-001) are likely caused by the combined arrival of CME with ID 2026-01-08T05:53:00-CME-001 (see notifications 20260108-AL-001, 20260109-AL-002), CME with ID 2026-01-08T15:48:00-CME-001 (see notification 20260109-AL-003), CME with ID 2026-01-08T17:00:00-CME-001 (see notification 20260109-AL-001, 20260109-AL-003), and CME with ID 2026-01-08T17:12:00-CME-001 (see notification 20260109-AL-003).
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: 2026-01-12T10:05:00-RBE-001.
## Notes:
The arrival of these CMEs is also associated with geomagnetic storm with ID 2026-01-10T18:00:00-GST-001 (see notifications 20260110-AL-004, 20260110-AL-005) and with magnetopause crossing with ID 2026-01-11T05:56:00-MPC-001 (see notification 20260111-AL-002).
