Activity ID: 2024-12-06T18:36:00-CME-001 (version 1)
Note Keyword:
GAP: Data gap

OFL: Moving/Opening field lines
Morphology Keyword:
L: Loop
Note: Very faint, puff-like CME seen to the SW in SOHO LASCO C2. The leading edge becomes completely diffuse before reaching halfway through C2's field-of-view. The source is uncertain. One candidate source is an area of dimming seen centered at about N10W40 starting at 2024-12-06T18:00Z in GOES SUVI 284, accompanied by a small amount of brightening from AR 13910 (N16W60) and/or AR 13918 (N13W57). Another candidate source is subtle field line movement on or beyond the NW limb seen in GOES SUVI 284/195. This CME was not captured in STEREO A COR2 due to a data gap which lasted from 2024-12-06T15:53Z to 2024-12-06T19:53Z.
