Hyderabadis awakened to a rare phenomenon of hallow ring round the sun that left everyone surprised.

What is Sun Halo and why it appears? 

The halo that appeared round the Sun may be a ring that appears thanks to the dispersion of sunshine as white light passes through ice crystals found in upper-level cirrus clouds, causing the halo to possess colours. consistent with the University of Illinois, “The halo may be a ring of sunshine 22-degrees from the Sun or Moon and is that the commonest sort of halo observed and formed by hexagonal ice crystals.”

The clouds contain many tiny ice crystals, which refract, split and even reflect the sunshine to offer an impact of a circular rainbow ring. The crystals need to be oriented and positioned with great care with reference to your eye, so as for the halo to seem .

A few days ago, an equivalent phenomenon was witnessed in Bengaluru also . during a 22-degree halo, the type seen in Bengaluru, light enters from one side of the snow mist and exits through another, being refracted on both entry and exit. the 2 refractions bend the sunshine by 22-degrees from its original point, producing a hoop of sunshine round the Sun or the Moon.

Seen round the Moon, lunar halos are mostly colourless as moonlight isn’t very bright. However, within the case of the Sun, these colours are more noticeable and appear as bright as a rainbow.
