Comet 2020V2 ZTF passed near the celestial north pole from the end of 2022 to the beginning of 2023. The comet has moved to the region of Cassiopeia, positioned about 3.5 degrees northwest of εCas on this day. The brightness of the coma was 10th magnitude, and a dust tail about 10 arc minutes long was observed in the north direction. The greenish ion components became less noticeable compared to that of my previous observation. The comet will move southward slowly from now on, and can be tracked in good condition in the western sky before midnight for a while.
  View angle: 0.7×0.7°
