How the score works

60% weight

Cloud cover

Averaged over the whole dark window, layer by layer. Low cloud blocks everything; thin high cirrus still lets bright stars through.

40% weight

Moon darkness

A new moon boosts the score. A bright Moon only costs points while it is actually above the horizon in the dark hours, and more the higher it stands.

What you can realistically see from the city

The Moon and the bright planets (Venus, Jupiter, Saturn, Mars when it is close) show up even from a light-polluted centre on a clear night.
Bright stars and constellations are easy. Through binoculars, the Pleiades and the Orion Nebula (winter) still stand out; faint galaxies do not.

Darkness through the year

From about 27 May to 15 July the sun never gets 18° below the horizon, so the sky never becomes fully dark, even at 2 a.m.
Around the winter solstice you get about 12 hours of full darkness.
Nights with 9+ hours of full darkness: October – February.
The bright core of the Milky Way (in Sagittarius) never climbs more than 10° above the southern horizon from Liège, so it hides behind haze and buildings.
The summer Milky Way through Cygnus is the one to look for: its brightest star, Deneb, passes 85° high.
