In pics: Rainbow-coloured sun halo sighted in Dehradun
Sun halo occurs due to sunlight refracting in millions of hexagonal ice crystals suspended in the atmosphere.
A rainbow-coloured sun halo was sighted in Uttarakhand’s Dehradun on Sunday afternoon prompting the residents to record the unusual visual spectacle on their mobile phones.
The residents also uploaded it on social media where it soon became viral.

A rare optic phenomenon, the sun halo appears like a rainbow encircling the sun or moon at a radius of approximately 22 degrees. (Photo: Twitter/juyal_rishita)

A sun halo, also known as a 22-degree halo, is visible just like a rainbow when viewed from the right angle - sometimes appearing just white but often with colours of the spectrum also clearly present. (Photo: Twitter/herumbpushkar)
Halos are produced by cirrus clouds, which are thin, detached, hair-like clouds. These clouds are formed very high up in the atmosphere, over 20,000 feet.
