M22 Observation Details
M22 Daily Motion
M22 will be visible until January, 1, 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.

M22 - Sagittarius Cluster
The Sagittarius Cluster (M22) is a globular cluster located in the constellation Sagittarius. It was discovered by Abraham Ihle in 1665 and included in Messier's catalog in 1764. M22 is one of the brightest and closest globular clusters to Earth.
M22 spans about 97 light-years across and contains over 100,000 stars. The cluster is approximately 10,600 light-years away from Earth and has an apparent magnitude of 5.1, making it visible to the naked eye and easily seen 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 M22 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.
