2020 November 16 Sun - AR12781 farewell with some fine firework

AR12781 has turned to the backside, leaving just a small patch of plages on the W limb. However, the filaments from AR12781 give off a firework show.
This is an animation of the eruptive firework, compiled from 67 frames taken from 02:43 UTC to 03:28 UTC.
Sorry for some field rotation because I use altazimuth mount.
Sunspot count: group=0. sunspots=0, R=0

Telescope: Lunt LS50T with B600 blocking filter
Camera : ASI174MM
exposure: 14.6 ms
approximately south is up, east to the left
