Air mirage over Munich

In clear air, the Alps are visible from Munich. In the morning of October 18, 2012, Frank Sievers observed this superior mirage of the Alps from the roof of a house behind the Perlach heat and power station. It was probably caused by layers of air of different temperature generated by the power station, which refract the light at different angles to the observer´s eye.

One day later, in the morning of October 19, 2012, the unusual mirage was visible again. This photo taken Stefan Rubach from the same Rooftop.
