Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-08-27T20:38Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-08-27T20:38:00-CME-001 (version 1)
Source Location: N10E09
Active Region Number: 14198
Note Keyword:
Source Signature Keyword:
BR: Brightening
Morphology Keyword:
F: Flux Rope
Note: CME seen as a narrow flux rope CME to the NE in STEREO A COR2 and as an extremely faint and wider flux rope to the NNE in GOES CCOR-1. Source is a small eruption seen starting at 2025-08-27T20:02Z seen as brightening from AR 14198 (N10E09) and post-eruptive brightening seen surrounding the Active Region in SDO AIA 131/304. Not captured in real time by SOHO LASCO due to a data gap which began 2025-08-27T12:30Z.

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.
