When and how to see it

Atria is highest in the sky at midnight in June. From India (about 20° N) it climbs to about 1° above the horizon; from 50° N it never rises. To see it you need the naked eye, even from a town.

Heights are worked out for India and for 50° N. Set your location in Settings to see them for where you are.

For tonight's best time from your own town, the darkness and the Moon, open it on the map and see its "Tonight from your location" card.
