Bright cirrostratus halo display in the northmost Finland Muotkatunturin erämaa, Peltojoki

Vibrant and infrequent solar halos formed in columnal ice crystals of the high cirrostratus cloud spotted in the arctic wilderness. Rarities, such as 120° parhelion and Wegener arc, were observed along with more common, but well defined halos (: 22° ring, 22° upper and lower tangent arcs or circumnscribed halo, parhelia, parhelic circle and an infralateral arc).
