Brief Parhelic Circle and Sundog

Going for a walk at lunchtime proved well timed as this section of parhelic circle appeared for just a few minutes.

The sun was quite high at 55 degrees so I was a bit surprised to see a sundog as well, toward the left of the colourless arc.

At first I wondered if the brighter patch on the circle to the right was a 120 degree parhelion, but it didn't seem quite far enough away from the sun and was probably just a brighter patch of cirrus.
