Sub Sun Over Bow River...........
Thursday, 15 February 2007 - 5:41 PM SL Time |  | |
November 2, 2006 was a frosty but clear morning in western Canada. A few minutes after take-off from Calgary, Alberta, this spectacular subsun was visible over the Bow River, east of Calgary. The brightness was such that it basically washed out any colour from the photo. It was formed by the reflection of sunlight off of oriented, plate-shaped ice crystals. In order to produce such an unusually clear, sharp and bright display, these crystals must have been very well aligned. In the background is the Bow River showing meanders, oxbows and a wide flood plain.
Description:
============
A subsun is situated exactly as far below the horizon as the sun is above it. A subsun is a pure reflection halo. That is why a subsun is white.
Formation:
==========
A subsun is caused by the reflection of sunlight from the upper base face of plate-shaped ice crystals which are floating in an exactly uniform way. The plate-shaped ice crystals then have the same effect like a very smooth water surface which reflects the sunlight. A subsun can also be caused by double-orientated column-shaped ice?crystals. But these crystals are very rare. As the ice crystals have to be below the observer`s position, this halo can only be seen in freezing fog or from a plane.
