 Solar Halo and Sundog over Camelot

   May 18, 2022

    Solar halo over Camelot

   Photographer:  Daniele Cipollina

   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
   equivalent to 28 mm): ISO 100; f/6.3, 1/1600 second exposure
     * Arquata Scrivia, Italy Coordinates: 44.681, 8.900
