## Summary:
Update on CME 2025-08-30T20:09:00-CME-001 (see previous notifications 20250830-AL-005 and 20250830-AL-006), now simulated with CME with ID 2025-08-30T00:23:00-CME-001 (see notification 20250830-AL-004). 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 CMEs may affect OSIRIS-APEX and STEREO A (glancing blow). The combined leading edge of the CMEs will reach OSIRIS-APEX at 2025-09-01T18:28Z (plus minus 7 hours). The flank of the CMEs will reach STEREO A at 2025-09-01T08:00Z (plus minus 7 hours).
The simulation also indicates that the CMEs may impact NASA missions near Earth. Simulations indicate that the combined leading edge of the CMEs will reach NASA missions near Earth at about 2025-09-01T18:24Z (plus minus 7 hours). The roughly estimated expected range of the maximum Kp index is 7-9 (strong to extreme).
Updated CME parameters are:
1: Start time of the event: 2025-08-30T00:23Z.
Estimated speed: ~878 km/s.

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 OSIRIS-APEX (glancing blow). The flank of the CME may reach OSIRIS-APEX at 2025-08-30T21:00Z (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 2025-08-31T04:00Z (plus minus 7 hours). The roughly estimated expected range of the maximum Kp index is 3-5 (below minor to minor).
