Description
Four days ago, during a solar observation, a 22° halo suddenly appeared above Thessaloniki. This ring of light is an optical phenomenon, which takes place when sunlight is refracted through millions of tiny hexagonal ice crystals in the atmosphere, usulally found within thin, high-level clouds like cirrostatus.
