Callanish and Sundogs

One of the most amazing thing about living in the Outer Hebrides is how much there is to observe and learn. Sundogs are quite a common occurrence and not just here, but I'd never heard of them before I moved her and certainly didn't know how they were formed. 'A sundog is a concentrated patch of sunlight occasionally seen about 22° to the left or right of the Sun. Sundogs often form in pairs on either side of our daytime star when sunlight refracts through icy clouds containing hexagonal platecrystals aligned with their large, flat faces parallel to the ground' - skyandtelescope.com
