Due most frequently to reflections in cirrus clouds, or in this case from jet exhaust, sundogs form rainbow-like spots or streaks on either side of the sun, roughly 22 degrees on either side, the National Weather Service informs us.  

For more in-depth and fascinatingly obscure information, the Wikipedia sundog information page is at your service.
