The image from the sky camera of Syrjävaara has been turned to map position. The surrounding sources of light pollution are well visible because the snow on the ground, on the trees and the foggy sky reflect the lights. Now is the worst time. The picture shows how white/blue light is the most polluting. It spreads very far and everywhere.
First of all, the outdoor lighting must be replaced with lights below 3000K. There’s only little bit of blue in them. The amount of light pollution decreases and they are a better option for the health of people and nature. After that, you can think about the use, direction and amount of light. Illumination of Syrjävaara or any other place tens of kilometers away is an expensive bisnes.
