Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-05-06T18:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2025-05-06T18:24:00-CME-001 (version 5)
Source Location: N45W20
Note Keyword:
GAP: Data gap
Source Signature Keyword:
FIL: Filament eruption
Morphology Keyword:
F: Flux Rope
Note: CME seen to the northwest in SOHO LASCO C2, C3 and GOES CCOR1. Not seen in STEREO A COR2 due to a data gap from 2025-05-06T19:23Z to 2025-05-07T01:53Z. The source is a large-scale filament eruption occurring near N45W20 best seen in GOES SUVI 284 and SDO AIA 304 which begins to lift off as early as 2025-05-06T14:45Z. The full filament liftoff can be seen leaving the disk starting at 2025-05-06T17:00Z. The CME features include a faster protruding nose ahead of the bulk of the CME.

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 |
