Rings around the sun

A strange phenomenon was observed in Hua Hin and all over Thailand on Friday when the sun appeared to have a halo around it. Mystified locals emerged from their houses and consulted each other in hushed voices at the solar spectacle. The halo is actually caused by ice crystals in thin clouds in the upper atmosphere, the crystals behave like tiny lenses and as they are all similar in shape refract the light at 22 degrees which corresponds to the radius of the sun halo. Needless to say more lottery tickets were purchased in Thailand that day!
