Upside down rainbow spotted in the UK

"One of the most spectacular light shows observed on earth," author Donald Ahrens describes the rainbow in his text Meteorology Today. If observed carefully, you would find that the sun is always behind you when you face the rainbow and the center of the circular arc of the rainbow is in the opposite direction to the sun. But there have been sightings that have proved otherwise also.

An astronomer in Cambridge, UK, has captured on camera an "upside down rainbow", which is considered to be an anomaly of nature.

According to a report in the Telegraph, astronomer Dr Jacqueline Mitton captured the freak rainbow near her home in Cambridge. Normal rainbows are made when light penetrates raindrops and re-emerges out the other side in the same direction. But, the inverted types, known as circumzenithal arcs, are caused when sunlight bounces off ice crystals high in the atmosphere, sending the light rays back up.

"The conditions have to be just right: you need the right sort of ice crystals and the sky has to be clear," said Mitton. "We're not sure how big an area it was visible over, but it was certainly very impressive," she added. A spokesman for the Met Office confirmed the inverted rainbows are occasionally spotted in British skies. "It is convex to the sun and is formed by refraction in suitably-oriented ice crystals and may show vivid rainbow coloring, as in this case," he said

Well, we all know about the strange ways of nature and the even stranger creations, the 'upside down rainbow' is just another sense of humor by god, perhaps when the sky 'cries' with happiness!
