A 22° Ice Halo after Sunrise with
Spectacular Contrails and Crepuscular Rays
Michigan, 2015
Although rarer, you can see part of an "upper tangent arc".
(the bright region at the top of the halo)
Ice halos are caused by sunlight passing through high-altitude hexagonal shaped ice crystals
that have a certain orientation to the sun.
