Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-01-25T20:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-01-25T20:48:00-CME-001 (version 1)
Note Keyword:
OFL: Outflowing material at the back of the CME
Source Signature Keyword:
Morphology Keyword:
L: Loop
Note: Faint, wide CME seen to the N in SOHO LASCO C2/C3 and NE in STEREO COR2A. No source observed on the disk for this event, but it triangulates between coronagraphs to around N34W02. This CME begins to incredibly slowly evolve to the N as early as 2025-01-25T06:00Z, with brighter material slowly emerging around 2025-01-25T20:48Z that accelerates in later frames of SOHO LASCO C3 to its final speed.

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
