Where the nights are darkest

Krásné Pole has the darkest nights (brightness 3.3), then Polanka nad Odrou and Petřkovice. Half of the neighbourhoods are brighter than 16.7. Ranking of 24 neighbourhoods by the light a satellite sees at night.

How we calculate it

The mean night brightness at addresses in the neighbourhood from the VIIRS satellite over the last full year (a yearly composite in squares of about 500 m, nW/cm²/sr). It measures the light of street lamps, windows, signs and traffic that shines upwards: the lower the number, the darker the sky and the more stars. Right under a lamp it can be brighter than the number for its square says.

Without neighbourhoods with fewer than 2 000 residents: they are mostly fields or forest, and a handful of addresses would otherwise top every ranking. You’ll find them in the list of all neighbourhoods.
