In the Northern Hemisphere, it stays observable in good condition for a long time. In the Southern Hemisphere, it is not observable until 2023.

* C/2014 F3 ( Sheppard-Trujillo )

Now it is 20.3 mg (Oct. 30, 2021, Pan-STARRS 1, Haleakala). At the discovery, it was expected to be observable at 16-17 mag for a long time from 2020 to 2022. It had been lost for a long time since 2015, but the recent observations are found. Actually, it brigthens up to 20-21 mag at best.
