## 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 2025-11-02T07:05Z.
The elevated energetic electron flux levels observed since 2025-10-31T12:05Z are caused by the coronal hole high speed stream starting on 2025-10-28, reaching maximum sustained speeds of approximately 750 km/s (see notifications 20251031-AL-002, 20251031-AL-003). The solar wind speed observed at L1 is currently around 466 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.

## Summary:
C-type CME detected by STEREO A / SOHO.
Start time of the event: 2025-10-31T23:48Z.
Estimated speed: ~567 km/s.
Estimated opening half-angle: 32 deg.
Direction (lon./lat.): -46/-18 in Heliocentric Earth Equatorial coordinates.
Activity ID: 2025-10-31T23:48:00-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 this CME may affect BepiColombo, OSIRIS-APEX (glancing blow), Parker Solar Probe (glancing blow), and Solar Orbiter (glancing blow). The leading edge of the CME will reach BepiColombo at 2025-11-01T20:13Z and the flank of the CME may reach OSIRIS-APEX at 2025-11-03T16:00Z, Parker Solar Probe at 2025-11-03T04:00Z, and Solar Orbiter at 2025-11-03T15:00Z (plus minus 7 hours).
The simulation also indicates that the CME may have a glancing blow at NASA missions near Earth. Simulations indicate that the flank of the CME will reach NASA missions near Earth at about 2025-11-04T04:00Z (plus minus 7 hours). The roughly estimated expected range of the maximum Kp index is 3-4 (below minor).

## Summary:
C-type CME detected by STEREO A / GOES / SOHO.
Start time of the event: 2025-10-31T00:24Z.
Estimated speed: ~743 km/s.
Estimated opening half-angle: 33 deg.
Direction (lon./lat.): -97/-4 in Heliocentric Earth Equatorial coordinates.
Activity ID: 2025-10-31T00:24:00-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 Psyche (minor impact), Parker Solar Probe, and BepiColombo (glancing blow). The leading edge of the CME will reach Psyche at 2025-11-05T09:00Z, Parker Solar Probe at 2025-11-01T11:53Z (plus minus 7 hours). The flank of the CME will reach BepiColombo at 2025-10-31T19:00Z (plus minus 7 hours).

## Summary:
Significantly elevated energetic electron fluxes in the Earth's outer radiation belt. GOES "greater than 2.0 MeV" integral electron flux is above 1000 pfu starting at 2025-10-31T12:05Z.
The elevated energetic electron flux levels are caused by the coronal hole high speed stream starting on 2025-10-28, reaching maximum sustained speeds of approximately 750 km/s. The solar wind speed observed at L1 is currently around 678 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.
