CMHASD member Jim Burchell captured this superb Sun Halo on the 14th Dec 2022 around midday which lasted for quite a long time – over an hour. A Sun halo, also known as ’22 degree halo’, is an optical atmospheric phenomenon that occurs due to sunlight refracting in millions of hexagonal ice crystals suspended in the atmosphere.
More information about how Sun Halo’s are formed can be found on the Atmospheric Optics website.
