Sonic Boom Meets Sun Dog from barbara tomlinson on Vimeo.

Video from Kennedy Space Center Apollo Center February 11, 2010. Launch of Solar Dynamics Observatory on an Atlas V rocket. About 1 minute 14 seconds after liftoff the vehicle went supersonic. Keep watching to the 2 minute mark. The shock wave obliterated a sun dog. It was really beautiful, and poetic for this mission. A sun dog or parhelion is a bright rainbow effect in the sky caused by refraction of sunlight through ice crystals.
