   Summary Authors:  Marco Meniero;  Giovanni Tumino

   Shown above is a nighttime view of  lava streaming down a  flank
   of Mt Etna as viewed from Naxos Bay, Sicily, on June 9, 2022. Note the
   patch of light just above the glowing lava. This looks like it might be
   a  light pillar resulting from the glowing lava flow, however,
   according to  Marco Meniero, an expert on meteorological phenomena,
   it's actually  paraselene or moondog. The  Moon can be seen at
   the right side of the image. Note also the numerous  glitter paths
   (both photo).  Click here to see a video in timelapse.

   Photo details: Canon RA camera; SIGMA DG 50 mm lens; f/1,4;
   f/4,5; 4-second single-exposure; ISO 1600.
