    Solar Halo and Sundog over Camelot

       Solar halo over Camelot

      Summary Authors:  Daniele Cipollina;  Cadan Cummings   
      
      This stunning photo features a  solar halo along with two   
       sundogs visible in the sky near  Arquata Scrivia, Italy. Both   
      sundogs and solar halos are produced by  ice crystals suspended in   
      the atmosphere. The difference between the two optical phenomena is   
      caused by variations in ice crystals orientation. If the ice is   
      oriented horizontally to the viewer, a sundog is visible. Conversely,   
      where the ice crystals are randomly oriented, a solar halo is visible.   
      According to legend, the hill in the foreground of the photo was where   
       King Arthur's castle was built. Photo taken on August 12, 2015, at   
      20:41 GMT.   
      
      Photo details:; Nikon Coolpix P7100; focal length 6 mm (35 mm
