M15: Rise, Set, Nighttime Path
M15 Daily Motion
M15 will rise at 16:18, reaching 45° when twilight begins at 20:15. It will reach transit at 63° by 22:57 and will set before twilight ends at 05:36.M15 will be visible until January, 14, 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.

M15 - Pegasus Cluster
The Pegasus Cluster (M15) is a globular cluster located in the constellation Pegasus. It was discovered by Jean-Dominique Maraldi in 1746 and included in Messier's catalog in 1764. M15 is one of the most densely packed globular clusters known.
M15 spans about 175 light-years across and contains over 100,000 stars. The cluster is approximately 33,600 light-years away from Earth and has an apparent magnitude of 6.2, making it visible with binoculars or a small telescope.

The graph is structured with the vertical axis showing the hours of the day, ranging from 12 AM to 12 AM the next day, while the horizontal axis spans each day of the year.
The reddish shaded area indicates the periods when the M15 is above the horizon, visible to observers. The white line marks the times when the celestial object reaches its highest point in the sky each day, known as the transit.
