Sun Dog no longer there

As the rocket carrying the Solar Dynamics Observatory launched towards space, two atmospheric effects came together to give the crowd below an interesting show.

Sunlight refracting through ice crystals in the air created an effect called a Sun dog, whereby a cloud was lit up in a spectrum of colours (I thought that was a separate effect, an iridescent cloud, whereas a sun dog is a bright point created by the coming together of several arcs, but anyway).

The rocket breaking the local speed of sound at that layer of the atmosphere created a shock wave that rippled out from it. This is a more normal effect, but what happened next was videoed (see from the 1:50 point onwards, it is repeated twice thereafter).
