      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.
