Direction (lon./lat.): -79/5 in Heliocentric Earth Equatorial coordinates.
Activity ID: 2025-11-29T09:00:00-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 Parker Solar Probe.

## 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 2025-11-29T08:05Z.
The elevated energetic electron flux levels observed since 2025-11-25T12:50Z are caused by a coronal hole high speed stream which arrived on 2025-11-24, reaching a maximum speed of approximately 830 km/s (see notifications 20251125-AL-001, 20251125-AL-002 and 20251127-AL-001). The solar wind speed observed at L1 is currently around 600 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.
