this is so cool (sonic boom vs. sun dog)

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.
