   In the late morning on December 12, 2021, I saw a group of
    cirrocumulus clouds moving across the sky towards the  Sun. I
   quickly grabbed my camera and headed for an open area expecting some
   beautiful  cloud coronae and/or  iridescences. Both coronae and
   iridescences are phenomena produced by optical  diffraction when
   water vapor or ice crystals in the air unevenly scattered the incoming
   light wavelengths, similar to a  prism.

   My first sight was fortunately a perfect corona with vivid colors. As
   the clouds moved through the sky, sometimes the corona turned into an
   iridescence. After around 20 minutes, the show come to an end. As a
   note, it is always best practice to take  precautions when viewing
   or photographing near the Sun. During this event, I remembered to
   shield myself against the intense sunlight close to the zenith, hiding
   the sun behind the building or some trees.

   Photo details: Canon 6D with Canon 28-135mm lens at f/9, ISO 100 and
   1/3200s.
