The brightest steady point
Look west-northwest — Jupiter outshines every star and burns with a steady, un-twinkling light.
Count its moons
Steady 10×50 binoculars show up to four Galilean moons as tiny dots in a neat line — they shuffle position night to night.
Belts and moons
Even a small scope shows Jupiter's two dark cloud belts and the four bright moons swapping sides through the week.
Count the tiny dots strung in a neat line beside the planet — the Galilean moons, and they visibly change places from night to night. A small telescope adds Jupiter’s two dark cloud belts across its cream-coloured disk.
Jupiter is so big that more than 1,300 Earths could fit inside it!
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.

Will clouds get in the way?
Forecast says 0% cloud cover at the 9:04 PM viewing time (15% average across the night). A bright planet also cuts through thin haze with ease.

Jupiter shines at magnitude -1.8 tonight — as bright as the brightest stars. Planets shine with a steady light while stars twinkle — that steadiness is the giveaway.
