* C/2017 K2 ( PanSTARRS )

Now it is bright as 8.6 mag (July 4, Marco Goiato). It is observable at 7.5-8 mag for a long time from 2022 to 2023. In the Northern Hemisphere, it stays observable in good condition until autumn. However, it is not observable at the high light from autumn to 2023 summer. In the Southern Hemisphere, it stays observable in good condition for a long time.
