Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-08-29T17:09Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2025-08-29T17:09:00-CME-001 (version 1)
Note Keyword:
GAP: Data gap
Source Signature Keyword:
FIL: Filament eruption
Morphology Keyword:
Note: CME first seen to the SW in STEREO A COR2 starting at 2025-08-29T17:09Z. CME is also seen to the SW in SOHO LASCO C2/C3 and GOES CCOR-1. The early propagation in LASCO C3 is missed in real time due to a regularly scheduled downlink data gap in SOHO LASCO. The source of this CME is most likely a far-sided filament eruption seen in STA EUVI 304. The filament appears to lift off the disk around 2025-08-29T15:45Z but can be seen slowly rising for several hours prior to the eruption.

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 |
