      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.
