Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-09-11T06:24Z ( SOHO: LASCO/C2 )

All Detecting Spacecrafts:

SOHO: LASCO/C2

SOHO: LASCO/C3

STEREO A: SECCHI/COR2

Activity ID: 2026-09-11T06:24:00-CME-001 (version 1)

Note Keyword:

Source Signature Keyword:

OFL: Moving/Opening field lines

Morphology Keyword:

Note: CME visible to the NW in SOHO LASCO C2/C3 and STEREO A COR2. The CME is not visible in GOES CCOR-1 due to Earthshine. The potential source may be near the NW limb as seen from STEREO A EUV 195 imagery. A possible eruption with moving field lines can be seen around 2026-09-11T04:25Z. The CME overlaps in the field of view with the CME first seen in SOHO LASCO C2 at 2026-09-11T05:36Z.
