Magnificent 'Sun halo' delights Bengaluru residents

The phenomenon is popularly known as the 22-degree halo.

A bright 'Halo' around the sun was spotted in the sky around noon in Bengaluru on Monday. Locals enjoyed the spectacle in the sky, which looked as colourful as the colour of a rainbow.


The phenomenon is popularly known as the 22-degree halo because the ring has a radius of approximately 22 degrees around the sun or moon.


A 22-degree halo is an optical phenomenon that belongs to the family of ice-crystal halos. The halo of the sun or occasionally the Moon (also called a moon ring or winter halo), occurs when the sun’s or moon’s rays get deflected/ refracted through the hexagonal ice crystals present in cirrus clouds.


These clouds contain millions of tiny ice crystals, which refract, split and even reflect the light to give an impression of a circular rainbow ring. The crystals have to be oriented and positioned just so with respect to your eye, in order for the halo to appear.


While it may appear as a rare cosmic occurrence, a cursory Google search will reveal that halos are common phenomenons that are spotted regularly across the world.
