## Summary:
C-type CME detected by STEREO A / GOES / SOHO.
Start time of the event: 2025-07-21T14:09Z.
Estimated speed: ~625 km/s.
Estimated opening half-angle: 25 deg.
Direction (lon./lat.): -70/3 in Heliocentric Earth Equatorial coordinates.
Activity ID: 2025-07-21T14:09:00-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), BepiColombo (glancing blow), and Mars (glancing blow). The leading edge of the CME will reach Psyche at 2025-07-29T08:00Z (plus minus 7 hours). The flank of the CME will reach BepiColombo at 2025-07-22T19:00Z, and Mars at 2025-07-26T20:00Z (plus minus 7 hours).

## Summary:
C-type CME detected by STEREO A / GOES / SOHO.
Start time of the event: 2025-07-20T07:53Z.
Estimated speed: ~687 km/s.
Estimated opening half-angle: 36 deg.
Direction (lon./lat.): -41/-22 in Heliocentric Earth Equatorial coordinates.
Activity ID: 2025-07-20T07:53:00-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 Psyche (glancing blow), BepiColombo, OSIRIS-APEX (glancing blow), and Parker Solar Probe (glancing blow). The leading edge of the CME will reach BepiColombo at 2025-07-21T08:58Z (plus minus 7 hours). The flank of the CME may reach Psyche at 2025-07-26T18:00Z, OSIRIS-APEX at 2025-07-22T22:00Z, and Parker Solar Probe at 2025-07-22T06:00Z (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 2025-07-23T02:00Z (plus minus 7 hours). The roughly estimated expected range of the maximum Kp index is 4-6 (below minor to moderate).

## 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 2025-07-19T07:00Z.
The elevated energetic electron flux levels observed since 2025-07-14T15:25Z are caused by a coronal hole high speed stream which arrived on 2025-07-11, reaching a maximum speed of approximately 760 km/s (see notifications 20250714-AL-001, 20250714-AL-002, 20250716-AL-001, and 20250718-AL-001). The solar wind speed observed at L1 is currently around 400 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.
