I am always ready for a sun or moon dog and normally point out to others when I can tell one is about to form.
The sky conditions look really great November 4th as the sun was dipping behind the trees in the foreground.
(In the images you can see the glow in the trees).
I was expecting to see a Circumhorizontal arc but when I looked up, the arc was opposite of what I was expecting. Thought you might want to see it. Enjoy!

Actually, you did see a ,circumhorizontal arc, but not the near-horizon version below the sun (which you can only see with high sun elevation), but its counterpart near the zenith (which you only can see with lower sun elevations). Both arcs are parallel to the horizon, i.e. have the zenith as their centerpoints.
