The Observatory Floor · Live All-Sky Chart

The sky above you.

This is a real chart of your sky, drawn for this moment. The circle is your horizon and the centre is straight overhead. Every zodiac constellation sits where it actually is from where you are standing — with the Sun, the Moon, and the ecliptic they all travel along. Scrub the hours and watch the whole sky turn.

Positions are computed live from sidereal time and each constellation's real coordinates. Altitude is geometric — it ignores atmospheric refraction near the horizon, and it cannot know about daylight, cloud or city glow. Without permission for your location we assume a mid-northern latitude and estimate longitude from your time zone. How we compute things →
