 Bright Parhelion over Syracuse, Italy

   One afternoon this past fall, I decided to photograph the sky near my
   home in Syracuse, Italy. My friends Massimo Tamajo and Salvo Basile
   pointed out a bright  parhelion, shown above, near the western
   horizon. These colorful patches of light form when  sunlight
   interacts with hexagonal, plate-shaped  ice crystals -– sunlight
   enters one of the crystal’s side faces, exiting through an alternate
   side face. Look for them approximately  22-degrees from the Sun, at
   the same  solar altitude. If you’re lucky, you may see one or either
   side of the  Sun (parhelia). This one happened to be to the Sun's
   right. Note that unlike  rainbows, parhelia or sundogs are
   red-colored toward  the Sun, as is the case for all  22-degree
   halo-related phenomena. Photo taken on November 21, 2020.
