CELESTIAL STUDIES · SCHOOL OF EVERSHADE
The Observer's Wheel
The sky itself, computed — turn the wheel and see what the night is doing.
An honest word from the Tower. Nothing on this page is a picture of the sky — it is the sky, computed in your browser from the same astronomy the lessons teach: a published catalogue of the bright stars, the Sun and Moon placed by their real motions, and a horizon drawn for the latitude you give it. Times are local mean time — the Sun's own time for your longitude, which your clock may lead or follow by some minutes. Positions are good to about a degree: enough to find things with your own eyes, which is the entire point. The golden ring is the zodiac as the tradition drew it; the stars behind it have drifted since the signs were named, and where it matters, the page shows you both. Buenas noches — clear skies.
Up tonight
Look it up in the sky
Applies the Celestial Studies lessons — the turning sky, the Moon's phases, and the zodiac as history and as astronomy.
