Around 11.00 am this morning at Coimbatore there appeared a large round disc around the sun which lasted around two hours.Several theories were abounding in the neighborhood. One theory was this a unique phenomenon happens nonce in 100 years. Another rumor was that a great disaster is about to happen to the world. A third rumor that was floating was that a great man is about to die.On quickly looking up the Wikipedia I learned that this a unique optical phenomenon produced by ice crystals creating colored or white arcs and spots in the sky. I quickly rushed home to get my camera and was able to take a few shots of this rare spectacle which I have never witnessed before.This lasted for around 90 minutes and then the ring slowly dissipated. I am unable to explain the blue spots in the images - maybe a refraction from the camera lens.I think I was very very fortunate to see this glorious image in the sky. Did any one else see this phenomenon in your city?
