Stunning sight: A rare solar halo in the sky above Huangshan city, Anhui Province, in China. The effect is created when the sun shines through hexagonal crystals in high-altitude cirrus clouds
Very unusual sky… Called an ice halo, a larger version of sundogs that form when there are a large amount of ice crystals suspended high in the atmosphere
Chalmers University of Technology, Swedish architecture, HALO, solar panels…
Eclipse from 35 , 000 feet . Reminds me of Halo - the Game ?
