Watching high in the sky, I do see the circumzenithal arc. It is not contrasted, but something else is much more interesting: a supralateral arc and even a Parry supralateral arc. The first display is the big pale circle centered around the Sun tangent to the circumzenithal arc. The Parry supralateral arc is the colored patch in the supralateral arc located at 45° on the right of the Sun. Some German observators have noticed that this halo is visible only once a year!
