 Lunar Halo Above Evia, Greece

   February 01, 2021

    Moon Halo 2020-11-28

   Photographer:  Dimitris Malliaris
   Summary Authors:  Dimitris Malliaris;  Jim Foster
   Quite often I’m able to photograph interesting atmospheric phenomena
   from the backyard of my house in the central Evia region of Greece. In
   late November 2020, the  lunar halo shown above appeared a few hours
   after nightfall. As with their daytime counterparts ( solar halos),
   pencil-shaped, hexagonal  ice crystals that compose  cirrus
   clouds, and are more or less randomly oriented as they fall, are
   responsible for the ring that encircles  the Moon

   Note that to the left of the Moon (between the Moon and the halo) the
   open  star cluster called  the Pleiades, also known as the Seven
   Sisters, can be seen. Photo taken on November 28, 2020, at 20:59.
   Photo Details: Canon EOS 6D camera; Canon 24-105mm f/4 L IS USM lens;
   24mm focal length; ƒ/5 aperture;; 10 sec. exposure time; ISO:800; Adobe
   Photoshop CC (Windows).
