M12: Rise, Set, Nighttime Path
M12 Daily Motion
M12 will reach its transit before twilight, at 18:15. By the onset of twilight at 20:34, it will be at elevation, and it will set before sunrise, at 00:08.M12 will be visible until October, 17, 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 M12 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.
