From Ashburn (click to change), Alioth is visible in both the dusk and dawn skies. In the evening, it will become visible at around 19:08 (EDT) as the dusk sky fades, 24° above your north-western horizon. It will then sink towards the horizon, becoming tricky to observe after 20:53 when it dips 13° above your north-western horizon. At 03:21, it will return to an altitude of 13° above your north-eastern horizon, and reach an altitude of 34° before fading from view as dawn breaks at around 06:35.
