To make up for that last video, here's a video taken at Thursday's launch of the Solar Dynamics Observatory. According to SpaceWeather.com:
"Sundogs are formed by plate-shaped ice crystals floating in cirrus clouds. 'When SDO's Atlas V rocket penetrated the cirrus, shock waves went rippling through the cloud and destroyed the alignment of the crystals,' says atmospheric optics expert Les Cowley. 'This extinguished the sundog.'" To the cheers and delight of observers who can be heard in the background.
