22° Halo English Lake District

   22� radius halo English Lake District.

Imaged on 28th June 2002 by Ann Bowker (Mad about Mountains) while fell walking.

The halo colours show well. There is a distinct red inner edge fading away from the sun through oranges and yellows to blue. The inside is dark, a "hole in the sky", because no light is refracted there by ice crystals.

Above the sun and much closer to it than the halo there are some faint iridescent colours produced by diffraction of sunlight by very small cloud droplets and crystals.
