M37 Observation Details

M37

M37 Daily Motion

M37 will reach transit at 20:15. By the time twilight starts at 03:58 it will be at an elevation of 4° degrees and will set at 04:23, before twilight ends.
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.

M37 Image Gallery

DSS Blue

M37 photo taken with blue filter
These images are valuable for highlighting the presence of younger, hotter stars, which emit more light in the blue wavelengths.

DSS Red

M37 photo taken with red filter
These images are excellent for detecting older, cooler stars, as well as emission nebulae, which glow primarily in the red due to hydrogen alpha emissions.

DSS Near-Infrared

M37 photo taken with Near-Infrared filter
These images can penetrate dust clouds that obscure visible light, revealing structures and objects hidden within.

DSS Composite image

M37 color image
DSS Color images are composite images created by combining the blue, red, and often near-infrared images to produce a full-color representation.

The photos are taken from the Digitized Sky Survey 2 (DSS2), which was produced at the Space Telescope Science Institute (STScI) under NASA contract, using data from the UK Science and Technology Facilities Council (STFC), the European Southern Observatory (ESO), and the National Geographic Society-Palomar Observatory Sky Survey (POSS II).

Special thanks to the National Optical Astronomy Observatory (NOAO), the Royal Observatory, Edinburgh, and the California Institute of Technology for their significant contributions.

The graph illustrates the annual visibility pattern of a M37, providing a comprehensive overview of its daily appearances and transit times throughout the year.
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.
