EarthSky Facebook friend Birgit Bodén wrote from Sweden:
The rainbow color in the mist from the rising sun early this morning…. north of Vittjärv in northern Sweden …
Thank you, Birget!
Notice Birget specifically say this is a “rainbow,” just rainbow colors. It’s not a true rainbow because rainbows are always seen opposite the sun. We asked Les Cowley of the great website Atmospheric Optics how to describe this rainbow-like light. He said:
It’s possibly a corona caused by diffraction by nearby mist droplets.
It might even by produced by pollen (if pollen is still in season in Sweden).
Thank you, Birget, and thank you, Les!
