Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-11-13T19:53Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
Activity ID: 2025-11-13T19:53:00-CME-001 (version 1)
Note Keyword:
OVR: Event partially overlaps with another CME

Note: This CME is visible to the southeast in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2 imagery. Noting that this event is partially obscured by the pylon in SOHO LASCO C3 and GOES CCOR-1 imagery. This event overlaps with preceding CME: 2025-11-13T18:38Z. The source may be related to an eruption centered near S20E55 starting around 2025-11-13T19:40Z seen best in GOES SUVI 304 imagery. However, it is also possible this event is associated with the southeast filament eruption which was associated with CME: 2025-11-13T18:38Z.
