pillars to the zenith. Lauri Kangas (site)
saw these exceptionally tall light pillars in Ontario, Canada
in January '04.
" I managed to get a few images of light pillars that
were so tall they converged overhead at the zenith. It was bitterly
cold at -24C but there was no wind and there was a drizzle of
ice crystals falling from the sky." The light pillars appear
to converge towards the zenith because the plate shaped ice crystals
producing the reflections of lights on the ground are at different
heights in the atmosphere - more
