## Summary:
C-type CME detected by GOES.
Start time of the event: 2025-11-18T01:00Z.
Estimated speed: ~773 km/s.
Estimated opening half-angle: 24 deg.
Direction (lon./lat.): 114/27 in Heliocentric Earth Equatorial coordinates.
Activity ID: 2025-11-18T01:00:00-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 Juice (glancing blow). The flank of the CME may reach Juice at 2025-11-21T12:00Z (plus minus 7 hours).

## Summary:
Solar energetic particle event detected by STEREO A. The flux of 13-100 MeV protons exceeds 10^(-1) pfu/MeV starting at 2025-11-15T09:34Z.
NASA spacecraft at the orbits near STEREO A can be impacted.
Activity ID: 2025-11-15T09:34:00-SEP-001.
## Notes:
This SEP event (2025-11-15T09:35:00-SEP-001) may be associated with the Interplanetary Shock with ID 2025-11-15T15:56:00-IPS-001 and with the arrival of the CME with ID 2025-11-14T08:00:00-CME-001 (see notifications 20251114-AL-008, 20251114-AL-010). The STEREO A 13-100 MeV protons had been previously enhanced (but had already dipped below threshold before the start of the current SEP event) due to previous arrivals including the recent IPS: 2025-11-15T07:08Z associated with the arrival of CME: 2025-11-13T03:24Z.
