Bode's Galaxy (M81) Observation Details
M81 Daily Motion
M81 is circumpolar, never setting below the horizon and always visible in the night sky from your location. However, it will change its position significantly, moving 42 degrees over time. You can find the best times to observe M81, when it reaches its highest elevation, in the annual motion section.M81 will be visible until August, 9, 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.

M81 - Bode's Galaxy
Bode's Galaxy (M81) is a spiral galaxy located in the constellation Ursa Major. It was discovered by Johann Elert Bode in 1774 and later cataloged by Charles Messier. M81 is one of the brightest galaxies in the sky and is part of the M81 Group of galaxies.
M81 spans about 90,000 light-years across and contains a massive population of stars, gas, and dust. The galaxy is approximately 12 million light-years away from Earth and has an apparent magnitude of 6.9, 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 M81 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.
