Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-03-25T11:12Z ( SOHO: LASCO/C2 )

All Detecting Spacecrafts:

SOHO: LASCO/C2

SOHO: LASCO/C3

STEREO A: SECCHI/COR2

GOES: CCOR-1

Activity ID: 2026-03-25T11:12:00-CME-001 (version 1)

Note Keyword:

Faint: Faint event; may affect type assignment

OVR: Event partially overlaps with another CME

Source Signature Keyword:

OFL: Moving/Opening field lines

Morphology Keyword:

Note: Faint and narrow CME visible to the NE in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2 imagery. This CME appears to overlap the CME first seen in SOHO LASCO C2 at 2026-03-25T09:36Z. The source of this CME appears to be moving/opening field lines visible beyond the NE limb in GOES SUVI 284 starting around 09:00Z, overlaps source movement from CME: 2026-03-25T09:36Z.
