No, it's "halo phenomenon", similar to rainbow. This phenomenon can be seen when you watch in direction near to sun and see light interaction on water and ice particles. See https://en.wikipedia.org/wiki/Halo_(optical_phenomenon)
In this case, sun is near to left edge of picture, so you can see part of "halo circle" on trails.
