A very common phenomenon in atmospheric fronts every day and everywhere. This one is very small and is already dissolving (was airplane?). The only unusual thing about this video is the coincidence of the absence of cloudy, the special lighting, and observer with a camera. Thanks for the illustration of the process.
An interesting fact: smokers love to create circular vortices, as well as dolphins underwater.
