Astrophotography – Sun Hola

A halo is a ring or light that forms around the sun as the sun refracts off ice crystals present in a thin veil of cirrus clouds.

The halo is usually seen as a bright, white ring although sometimes it can have colour.

These rare meteorological optical phenomena occur when a thin layer of clouds moves past the sun.

These clouds are known as cirrus clouds and are typically made up of tiny ice particles.
