KnowraHalo (optical phenomenon)Linked fromLinked fromThe 7 pages that link to Halo (optical phenomenon), each with the reason it gives.All 7Broader topic 1Related 3Narrower topic 1Compared with 2Cirrus cloudRelated: Cirrus ice crystals can produce halos visible around the Sun or Moon.Atmospheric opticsBroader topic: Its geometry links visible rings and arcs to the shapes and orientations of cirrus-cloud crystals.Sun dogNarrower topic: Sun dogs belong to the broader family of ice-crystal halos.Cirrostratus cloudRelated: Hexagonal ice crystals in cirrostratus commonly refract light into 22-degree halos.Cirrostratus nebulosusRelated: Cirrostratus nebulosus commonly reveals itself through a halo around the Sun or Moon.HeiligenscheinCompared with: Atmospheric halos surround the light source, unlike Heiligenschein around the antisolar shadow point.Rainbow (optics)Compared with: Halos can resemble rainbows but usually form through refraction in ice rather than reflection inside water droplets.
