Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-12-08T05:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-12-08T05:12:00-CME-001 (version 2)
Source Location: S12W53
Active Region Number: 14298
Note Keyword:
DFL: Likely deflection of the event within the FOV
Source Signature Keyword:
FLR: Flare
Morphology Keyword:
F: Flux Rope
Note: CME first seen with the bulk to the NW in SOHO LASCO C2 starting at 2025-12-08T05:12Z. This CME is also seen to the NW in GOES CCOR-1 and to the NNE in STEREO A COR2. It is partially obscured by the pylon in SOHO LASCO C3. This CME is most likely related to an X1.1 flare from AR 14298 that peaked at 2025-12-08T05:01Z. The flare and associated eruption are best seen in GOES SUVI 304. The ejecta from the eruption experiences visible northward deflection.

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 |
