Weather pictures of the year 2011: lightning, auroras, snow and ice
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.
