GOES: CCOR-1
Activity ID: 2025-05-31T04:48:00-CME-001 (version 2)
Source Location: N06E41
Active Region Number: 14104
Note Keyword:
DFL: Likely deflection of the event within the FOV
OVR: Event partially overlaps with another CME
Source Signature Keyword:
PEA: Post eruption arcade
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
