2021 December 05 Sun - An eruptive prominence on the W limb, from remnants of AR12898. (part 1)

Observation starts at about 01:25 UTC and ends after 03:50 UTC.
My original schedule is to end the observation at 03:00 UTC. However, at about 02:36, I notice the formation of a loop on the W limb, and start a 30-minute recording.
Here is several selected frames of the loop. It will take a long time to process the >3600 frames to make an animation.

Telescope: Lunt LS100Tha with B1200 blocking filter + 2X barlow
Camera : ASI1600MM Pro, not cooled.
approximately north is up, east to the left.
