Light in the Arctic sky

Andy Pritchard was returning from a ski trip in the Finnish tourist center, when his eyes were opened to a fantastic film. As we approached the house, he looked around at the snowy slopes and heavenly saw the installation of 20 light poles.

"They sparkled in a row as a musical frequency visualization", — admired Pritchard.

Light pillars are formed due to ice crystals in the air, which "intercept" the light from the artificial light and distribute it into the vertical column. In contrast to the polar Aurora, of the phenomenon of solar activity is not required. The only ingredients are ice and light bulbs.

Color light columns depend on the type of light bulbs used in artificial light. Warm orange with the traditional sodium lamps high pressure and bright white comes from the new led lamps. The slopes in the saariselkä probably covered both of those.
