Any one consider what pilots think about Chemtrails.
Traveling through toxic dust should be a concern.
Or are they hushed like with the UFO sightings.
A sun dog or sundog (scientific name parhelion, plural parhelia, for "beside the sun". Also called a mock sun.) is a particular type of ice halo. It is a colored patch of light to the left or right of the sun, 22 (or more) degrees distant and at the same distance above the horizon as the sun. It is the most commonly or second most commonly seen of the ice halos. Sundogs can be seen anywhere in the world during any season. In Europe or USA they might be seen 1-2 times a week but not always obviously bright. They are best seen and at their most conspicuous when the sun is low. They are not rainbows.
Formation and characteristics
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.
Sundog forming rays enter a near vertical prism side face of a crystal and exit through a second side face inclined 60-degrees to the first. There is net refraction at each face and the light is dispersed into colors. There is no single angle of deviation through the crystal, which effectively acts as a 60 degree prism, but the minimum angle of deviation is ~22 degrees. This correspond to the distance of the inner edge of the sundog from the sun when the sun is low.
