Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-17T09:12Z ( SOHO: LASCO/C2 )

All Detecting Spacecrafts:

SOHO: LASCO/C2

STEREO A: SECCHI/COR2

Activity ID: 2025-04-17T09:12:00-CME-001 (version 2)

Note Keyword:

Faint: Faint event; may affect type assignment

Source Signature Keyword:

OFL: Moving/Opening field lines

Morphology Keyword:

J: Jet

Note: Narrow jet CME seen to the northeast in just one frame of SOHO LASCO C2 before a data gap obscures the CME; it is seen farther out into the field of view in STEREO A COR2; the CME likely originates from the far-side or just beyond the northeast limb as suggested by triangulation using STEREO A and SOHO imagery.
