M2 Observation Details
M2 Daily Motion
M2 will rise at 14:31, reaching 39° when twilight begins at 18:02. It will reach transit at 52° by 20:28 and will set before twilight ends at 02:24.M2 will be visible until January, 5, 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.

Where is M2 right now?
M2 is located in the constellation Aquarius, at right ascension 21h 33m 27s" and declination 00° 49' 23s. At the current time, it is below the horizon and not visible from your location.M2 - Globular Cluster
M2 is a globular cluster located in the constellation Aquarius. It was discovered by Jean-Dominique Maraldi in 1746 and later included in Messier's catalog in 1760. This cluster is one of the largest and oldest known globular clusters.
M2 spans about 175 light-years across and contains over 150,000 stars. The cluster is densely packed at its core, making it appear very bright. M2 is approximately 55,000 light-years away from Earth and has an apparent magnitude of 6.5, making it visible with binoculars or a small telescope.
