 Cloud Corona Above Syracuse, Italy

   April 08, 2021

    Diurnal Nebulae or Iridescence Clouds LD

   Photographer:  Dario Giannobile
   Summary Authors:  Dario Giannobile;  Jim Foster

   The photo above shows the lovely, pastel colors I noticed in the
   western sky before sunset, near my home in Syracuse, (Sicily) Italy. It
   was taken on February 13, 2021. These colors aren’t associated with
    sunset or twilight, however. Rather they result from the
    diffraction of sunlight by tiny, uniform-sized  droplets that
   compose  mid-level clouds that happen to be in the vicinity of
    the Sun. This is a cloud  corona. Its colors, filaments and
   structure resemble  nebula I sometimes see when peering through my
   telescope.

   Photo Details: Canon 6d camera; Sigma 150-600 lens; f/11; ISO 100;
   1/3200 second exposure.
