M41 Observation Details
M41 Daily Motion
M41 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.

M41 - Open Cluster
M41 is an open cluster located in the constellation Canis Major. It was discovered by Giovanni Batista Hodierna before 1654 and independently by Charles Messier in 1765. The cluster contains a mix of young, hot stars and older stars.
M41 spans about 25 light-years across and contains around 100 stars. The cluster is approximately 2,300 light-years away from Earth and has an apparent magnitude of 4.5, making it visible to the naked eye under dark skies and easily seen with binoculars or a small telescope.

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 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 M41 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.
