M37 Observation Details
M37 Daily Motion
M37 will rise before twilight begins, at 16:44, and will reach 41° elevation by the time twilight commences at 20:46. It will reach its transit at 84° by 00:48 and gradually fade away as the night ends at 06:14, maintaining an elevation of around 26°.M37 will be visible until May, 6, 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.

M37 - Open Cluster
M37 is an open cluster located in the constellation Auriga. It was discovered by Giovanni Battista Hodierna before 1654 and independently by Charles Messier in 1764. The cluster is the richest and brightest of the three open clusters in Auriga (M36, M37, and M38).
M37 spans about 20 light-years across and contains around 500 stars. The cluster is approximately 4,500 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 M37 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.
