## Summary:

Multiple CMEs have been detected as follows:
1: C-type CME detected by SOHO. 

Start time of the event: 2023-11-28T20:24Z.

Estimated speed: ~910 km/s.

Estimated opening half-angle: 45 deg.

Direction (lon./lat.): 13/0 in Heliocentric Earth Equatorial coordinates.

Activity ID: 2023-11-28T20:24:00-CME-001

2: C-type CME detected by STEREO A / SOHO. 

Start time of the event: 2023-11-28T20:48Z.

Estimated speed: ~768 km/s.

Estimated opening half-angle: 45 deg.

Direction (lon./lat.): 2/-6 in Heliocentric Earth Equatorial coordinates.

Activity ID: 2023-11-28T20:48:00-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 the CMEs may affect OSIRIS-APEX, Psyche, Solar Orbiter, and STEREO A. The combined leading edge of the CMEs will reach OSIRIS-APEX at 2023-11-30T09:11Z, Psyche at 2023-12-01T15:12Z, Solar Orbiter at 2023-11-30T22:24Z, and STEREO A at 2023-12-01T04:50Z (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 2023-12-01T06:45Z (plus minus 7 hours). The roughly estimated expected range of the maximum Kp index is 5-7 (minor to strong).
