Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-03-06T04:18Z ( SOHO: LASCO/C2 )

All Detecting Spacecrafts:

SOHO: LASCO/C2

SOHO: LASCO/C3

STEREO A: SECCHI/COR2

Activity ID: 2026-03-06T04:18:00-CME-001 (version 3)

Note Keyword:

Faint: Faint event; may affect type assignment

Source Signature Keyword:

Morphology Keyword:

O: Other

Note: Faint CME observed to the NW in SOHO LASCO C2/C3 and GOES CCOR-1, start time difficult to resolve in LASCO C2 but the CME becomes better defined further into the coronagraphs' field of view. May be faintly visible to the NW in STEREO A COR2, but too faint to resolve well, particularly in running difference imagery. The source is not clearly observed anywhere on disk.
