A special weather phenomena, known as a sun halo, was spotted around the sun over Merseyside today as these stunning pictures show.

They can be an impressive sight when witnessed, but what are they and what do they mean ?. Read on to find out:

  • They are an optical phenomenon produced by light interacting with ice crystals suspended in the atmosphere.
  • The crystals bend direct sunlight, dispersing the light into colours and projecting it elsewhere into the sky, at a usual 22 degree angle a halo can be seen around the sun.
  • They often do mean that rain is going to fall within the next 24 hours as the cirrostratus clouds that cause them can signify an approaching frontal system.
