 Splendid Sundog over Montreal, Canada

   January 24, 2023

   Summary Author:  Raymond Murphy;  Jim Foster

   Featured above is a colorful, right  sundog (parhelion) as observed
   from near Montreal, Quebec on the morning of November 26, 2022. You can
   tell it’s on the right side of the Sun because with  halos the red
   color is nearest the solar disk, unlike with rainbows. Sundogs are one
   of the most commonly observed optical phenomena. Look for them some
   22-degrees away from the Sun, at the same solar altitude, whenever
    cirrus clouds (composed of  ice crystals) are in the sky. Note
   that the puffy cloud in the foreground is a  cumulus type cloud --
   composed of water droplets. The "tail" of this sundog is actually a
   portion of the  parhelic circle. Always  be careful when looking
   anywhere in the vicinity of the Sun.
