Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-12-06T19:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-12-06T19:48:00-CME-001 (version 2)
Source Location: N23E10
Active Region Number: 14299
Note Keyword:
Source Signature Keyword:
FLR: Flare
FIL: Filament eruption
OFL: Moving/Opening field lines
BR: Brightening
DIM: Dimming
EUVW: EUV Wave
Morphology Keyword:
Note: CME first seen to the NNE in SOHO LASCO C2. The CME is also seen in GOES CCOR-1 and STEREO A COR2. This CME is most likely associated with an M1.1 flare from AR 14299 that peaked at 2025-12-06T19:21Z. The flare an accompanying eruption can be seen across GOES wavelengths but is best seen in GOES SUVI 304 and GOES SUVI 131. A nearby filament to the NE of the AR can be seen erupting, best seen in GOES SUVI 195/304. The eruption is also visible from the point of view of STEREO A EUV 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 |
