Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-11-16T15:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2025-11-16T15:24:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
Source Signature Keyword:
FIL: Filament eruption
Morphology Keyword:
J: Jet
Note: Faint, narrow, asymmetrical CME seen to the NW in SOHO LASCO C2 and GOES CCOR-1 coronagraphs. Not seen in STEREO A COR2 coronagraph. One potential source could be a narrow prominence eruption off/behind the NW limb seen in GOES SUVI 304 coronagraph at 2025-11-16T14:32Z, with longitude of 30 degrees. The source of this eruption and CME could be AR 4274 (N25W96.8) which is behind the limb.

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.

The CME is not seen in STEREO A coronagraph and although its source is likely on/close to the NW limb (and possibly is AR 4274 right behind the limb) only the plane-of-sky analysis is definitive.
