On a loopy aerial approach to Indianapolis airport. this excellent example of a lower sun pillar, with embedded “subsun”, became visible in fine ice-crystal clouds. The optical phenomenon was very bright in mid–late morning of late winter, and I had to expose for it at the expense of the snow-covered subdivisions below. Full sun pillars extend below the sun as well, when the atmosphere (instead of ground) and embedded ice crystals are there to revel them. Sometimes the lower pillars contain a concentration of reflected sunlight called a subsun, always directly below the real sun.
