Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-09-13T10:23Z ( STEREO A: SECCHI/COR2 )

All Detecting Spacecrafts:

STEREO A: SECCHI/COR2

Activity ID: 2026-09-13T10:23:00-CME-001 (version 1)

Note Keyword:

FF: Event fails/disappears before exiting COR2

Source Signature Keyword:

OFL: Moving/Opening field lines

Morphology Keyword:

Note: CME first seen to the W in STEREO A COR2 starting at 2026-09-13T10:23Z and fades before leaving the FOV of STEREO A COR2. This feature is not see in SOHO LASCO C2/C3 or in GOES CCOR-1. The source is likely related to field line movement seen beyond the WNW limb in STA EUVI 195 beginning after 2026-09-13T08:00Z.
