Design:
The reverse design by Tony Bianco features a nighttime scene on an extremely cold winter night in Canada. Above the engraved city streets, the clear night sky is coloured and enhanced with invisible black light technology, which re-creates the light pillar optical phenomenon when activated by ultraviolet light. The obverse features the effigy of Her Majesty Queen Elizabeth II by Susanna Blunt.
"This phenomenon is unique in that it is most often seen near man-made lighting, and onlyunder certain atmospheric conditions. I wanted to present it in a way that connects it to our daily urban lives-like an evening trip downtown, where we're surprised with an uncommon sight in a common place." Tony Bianco, Artist
Did you knowÃ
Light pillars may look like they're just anextension of a light source, but they're not physically above it. That vertical line is justhow our eyes interpret the collective beams of millions of ice crystals, which are located roughly halfway between you and the light source.
The setting sun and the moon can also cause solar or moon pillars. But our illuminated towns and citiesare the most common source of light in Canadafor this atmospheric optical illusion.
This atmospheric optical illusion typically occurs in the world's polar regions-including the Great White North-but light pillars can also occur further south when an Arctic cold mass moves in, bringing with it bitter-cold temperatures.
