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.
