Tonight's sky

What's above you right now. We'll check planet positions, the moon's phase, when it gets properly dark, and what you can realistically see without equipment.

How to read this

Altitude is how high above your horizon an object sits — 0° is right on the horizon, 90° is straight up. Anything below about 10° is usually lost in the haze near the ground.

Direction (azimuth) tells you where to look, measured clockwise from north. 0°/360° is due north, 90° is due east, 180° is due south, 270° is due west.

Brightness is magnitude — a scale where smaller numbers are brighter. Venus at magnitude −4 is easy to see even before full dark. A star at magnitude 6 is roughly the naked-eye limit under a truly dark sky.
