M52 Observation Details

M52 Daily Motion
M52 will be visible throughout the entire night. It will rise at 20:54, just before twilight begins, and will be at 20° when twilight starts at 00:03. It will reach its transit at 28° at 02:53, and will fade away as twilight ends at 06:15, being at 18° elevation.M52 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.

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 M52 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.
