Tonight's timeline

It rises at 2:42 AM and reaches 42° above the horizon at its best.
Spot the red dot
Look east after dark. Mars shows a distinct orange-red tint, warmer than the stars around it.
A firmer point
Binoculars steady the colour but won't show a disk. Use them to pick Mars out of the twilight glow.
A tiny disk
A scope shows a small ruddy disk. Detail depends on altitude and how close Mars is this year; steady nights reward patience.
Watch its colour against the stars nearby: Mars glows a steady ember-orange while true stars flicker white. Through a telescope in the months around an opposition, look for a bright polar cap and dusky surface markings.
Mars looks red because its dust is full of rust, a whole planet of orange chalk!
SKY DARKNESS
Bortle 9Bright inner-city sky: expect only the Moon, planets, and a handful of the very brightest stars. The Moon, planets and the ISS shine right through city glow.
