Callanish, Moon Halo and Moon Dogs Coaster

About the Artwork

A slightly surreal evening at Callanish with a moon halo and moon dogs. A 22° Halo around the moon is not uncommon this was the first and so far only time I’ve ever seen it with moon dogs though.

‘A moon dog, Moondog, or mock moon (scientific name paraselene, plural paraselenae, meaning "beside the moon") is a relatively rare bright circular spot on a lunar halo caused by the refraction of moonlight by hexagonal-plate-shaped ice crystals in cirrus or cirrostratus clouds.

Moon dogs appear as part of the 22° halo, roughly 10 Moon diameters outside the Moon.[3] They are exactly analogous to sun dogs, but are rarer because the Moon must be bright, about a quarter moon or more, for the moon dogs to be observed. Moon dogs show little color to the unaided human eye because their light is not bright enough to activate the cone cells.’ [https://en.wikipedia.org/wiki/Moon_dog]
