Alioth 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 68 degrees over time. You can find the best times to observe Alioth, when it reaches its highest elevation, in the annual motion section.Alioth will be visible until September, 27, 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.
