"Solar Dynamics Observatory Launch, Feb 11, 2010 -- A sun dog is a prismatic bright spot in the sky caused by sun shining through ice crystals. The Atlas V rocket exceeded the speed of sound in this layer of ice crystals, making the shock wave visible from the ground. The announcer can be heard in the video saying: The vehicle is now supersonic."
