M109: Rise, Set, Nighttime Path
M109 Daily Motion
M109 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 73 degrees over time. You can find the best times to observe M109, when it reaches its highest elevation, in the annual motion section.M109 will become visible in October, 4. After being too close to the Sun to observe, it will reappear in the night sky. Starting from October, 4, M109 can be seen again, providing a good opportunity for observation.
