Note: This CME is visible to the southeast in SOHO LASCO C2 imagery for a few frames before becoming diffuse to track the leading edge. The source is likely related to a C9.5 flare from Active Region 13932 (S18E49) peaking at 2024-12-21T23:05Z as seen in GOES SUVI 131, as well as ejecta launched from the same region seen in GOES SUVI 304.
