Sun Portal – Parhelion, originally uploaded by Zen Roxy.

A gorgeous parhelion (“Sundogs are made commonly of plate-shaped hexagonal ice crystals in high and cold cirrus clouds or, during very cold weather, by ice crystals called diamond dust drifting in the air at low levels. These crystals act as prisms, bending the light rays passing through them with a minimum deflection of 22°. If the crystals are randomly oriented, a complete ring around the sun is seen — a halo. But often, as the crystals sink through the air they become vertically aligned, so sunlight is refracted horizontally — in this case, sundogs are seen.”) in Norway.

Enjoy today’s photo! If you like the photo, please drop a comment to the original photographer at Flickr.
