   The photo above features a classic  sun pillar as observed just
   after sunset from the  southern end of La Palma (Canary Islands) on
   May 29, 2022. Pillars are  reflection phenomenon – sunlight (in this
   case) is reflecting off  hexagonal ice crystals in  high altitude
   clouds or off crystals that are free falling in the atmosphere. But for
   these wondrous vertical beams to form, the crystals must all be
   similarly oriented and tipped a bit in the direction of the viewer.
