leaving school this morning I was fortunate to witness 2 sundogs in the sky....AND I had my camera! :clap:
The sparkly stuff in the shot is floating ice crystals.

What is a sundog you ask? From wikipedia:
A sun dog or sundog (also called a mock sun) is an atmospheric phenomenon that creates bright spots of light in the sky, often on a luminous ring or halo on either side of the sun.(formed by ice crystals)
Sundogs may appear as a colored patch of light to the left or right of the sun, 22° (distant and at the same distance above the horizon as the sun, and in ice halos. They can be seen anywhere in the world during any season, but they are not always obvious or bright. Sundogs are best seen and are most conspicuous when the sun is low. Sundogs are formed by plate shaped hexagonal ice crystals in high and cold cirrus clouds or - during very cold weather - by ice crystals called diamond dust drifting in the air at low level.
Sun dogs orrur when the sun is at a 45 degree angle and the sun is at its lowest point.
As the sun rises higher the rays passing through the crystals are increasingly skewed from the horizontal plane. Their angle of deviation increases and the sundogs move further from the sun.However, they always stay at the same altitude as the sun.
Sundogs are red colored at the side nearest the sun. Farther out the colors grade through oranges to blue. However, the colors overlap considerably and so are muted, never pure or saturated. The colors of the sundog finally merge into the white of the parhelic circle (if the latter is visible).
