Supersonic shock sun dog

This video shows an Atlas V rocket carrying the Solar Dynamic Observatory satellite into orbit. As it ascends - approximately 1m56s into this video - you can see the supersonic shock front destroy a sun dog. Sun dog's are caused by sunlight being refracted by ice crystals in the Earth's atmosphere. Due to the crystals' geometry and the refractive properties of ice, sundogs always appear 22 degrees on either side of the sun, sometimes forming an entire circle. 22 degrees is a bit more that the span of your fingers held at arm's length.

I think it's imperative that someone forms a band called Supersonic shock sun dog.
