Visibility Unclassified

Tuomas Salo, Ursa (Helsinki)

I photographed the rising of the sun reflected from the clouds as an orange light. At the edge of the sun, the effect of refraction caused by different layers of the atmosphere is seen as distortions that cause weaving.

  Mirage is a light phenomenon that occurs when there are layers of air of different temperatures in the atmosphere. The light gets reflected between these different layers.
  
  This can happen, for example, in the spring over the water when the sea is still cold and the sun is already heating up the air .
  
  In mirages, distant objects may appear even if you do not otherwise see them. Their shape is more or less distorted. Objects like boats or islands may also appear to be hanging upside down in the sky.
  
  Mirages involving landscape objects and celestial bodies are reported to the Skywarden. Asphalt mirages are not collected, since they are quite common during the summer months.
