Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-03-11T18:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-03-11T18:24:00-CME-001 (version 1)
Note Keyword:
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
J: Jet
Note: Narrow, relatively fast CME seen to the northeast in SOHO LASCO C2 imagery and more directed towards the north in STEREO Ahead COR2 imagery composed of a fainter, faster shock. No sources on the Earth-facing disk in EUV imagery seem to be associated with this event, so the CME is likely associated with far-sided eruptive activity.
