A rainbow ring loops around the sun in a picture taken from Vancouver, Canada, and recently submitted to National Geographic's Your Shot. The solar halo is an optical effect created by ice crystals in high-altitude clouds, which refract sunlight and split it into its component colors.

Sky Phenomena: Sun Dogs: " atmospheric phenomenon that creates bright spots of light in the sky, often on a luminous ring or halo on either side of the sun. Sundogs may appear as a colored patch of light to the left or right of the sun, 22° distant and at the same distance above the horizon as the sun, and in ice halos. They can be seen anywhere in the world during any season, but they are not always obvious or bright. Sundogs are best seen and are most conspicuous when the sun is low."

Not every cloud has a silver lining; this multi-coloured cloud looks as if a rainbow has formed high in the heavens. The phenomenom - called a sundog - happens when ice crystals appear in clouds and refract the sun's rays. Photographer Robert Arn captured the cloud in Heyworth, Illinois, America.

This picture was taken the morning of the 2000 Winter Solstice near Ames, Iowa. The halo is made by sunlight shining through millions of ice crystals.
