A sunrise takeoff lead to a perfect view of these sundogs. Sundogs are caused by the refraction of light through ice crystals; essentially, they are ice particle reflections.
Sundogs only occur in rather cold temperatures; these are the result of -27C (-17F).
Greetings from the cold but spectacular north. 🙂
As Penny requested, I am re-posting this photo for the solstice. Happy December 21. 🙂 Please visit her site: http://icelandpenny.com/2021/12/15/300-metres/
