Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-09-21T11:38Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2023-09-21T11:38:00-CME-001 (version 1)
Note Keyword:
FF: Event fails/disappears before exiting COR2
OVR: Event partially overlaps with another CME
Source Signature Keyword:
Morphology Keyword:
Note: This CME is visible to the SE in SOHO LASCO C2/C3 and STEREO A COR2 coronagraph imagery. The start time is uncertain as the CME appears faintly and remains stationary in coronagraph imagery for a few hours, but becomes most apparent around 2023-09-21T11:38Z. The source is likely far-sided as there are no clear source signatures on the Earth facing disk. This CME partially overlaps with CME: 2023-09-21T13:38Z.
