Osuipa over there in the distance the spool lliikennöivä Naantali Finnlines Finnswankin "levitate", or so it brings the vessel shape to at least a strong look.

      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.
