Sun’s Halo
26/05/2021

Tags:

Context:

  • A rainbow around the Sun know as a Sun halo, was observed recently in Bengaluru.

About:

  • The halo that appeared around the Sun is a 22-degree ring that appears due to the dispersion of light as white light passes through ice crystals found in upper-level cirrus clouds, causing the halo to have colours.
  • The 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.
