Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-02T09:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-04-02T09:24:00-CME-001 (version 1)

Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
J: Jet
Note: Narrow, jet-like CME seen accelerating to the northeast primarily in SOHO LASCO C2 and also farther to the north in STEREO A COR2; the CME is with low confidence associated with a minor eruption with northern deflection from the northeastern side of Active Region 14046 (N10E10) seen starting around 2025-04-02T08:44Z in GOES SUVI 284 imagery, but triangulation suggests that the eruption originates from the far-side, and indeed, moving field lines are seen off the northeast limb primarily in GOES SUVI 284 imagery.

Prime?"primary flag" which is either True or False. If there are multiple CME analysis entries for a single CME, this flag would indicate which analysis is considered most accurate per measurement type. This is a helpful flag if you would like to download only one most accurate CME analysis per CME per Measurement Type
