C/2023 R2 (PANSTARRS) Daily Motion
C/2023 R2 (PANSTARRS) is circumpolar, never setting below the horizon and always visible in the night sky from your location. However, it will change its position significantly, moving 54 degrees over time. You can find the best times to observe C/2023 R2 (PANSTARRS), when it reaches its highest elevation, in the annual motion section.90004801 C/2023 R2 (PANSTARRS) will be visible until March, 7, when it will move too close to the Sun. During this time, its proximity to the Sun will cause it to disappear from the night sky, making it unobservable for a while.
