M13: Rise, Set, Nighttime Path
M13 Daily Motion
M13 will reach its transit before twilight, at 18:10. By the onset of twilight at 20:15, it will be at elevation, and it will set before sunrise, at 02:36.M13 will be visible until November, 24, 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.

M13 - Great Hercules Cluster
The Great Hercules Cluster (M13) is a globular cluster located in the constellation Hercules. It was discovered by Edmond Halley in 1714 and included in Messier's catalog in 1764. M13 is one of the most prominent and well-known globular clusters in the northern hemisphere.
M13 spans about 145 light-years across and contains several hundred thousand stars. The cluster is approximately 22,200 light-years away from Earth and has an apparent magnitude of 5.8, making it visible to the naked eye under dark skies 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 M13 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.
