Thats the correct term for it, Circumhorizontal Arc. Theres some info for ya.

I think it might simply be the shadow of the moon itself. It appears to also cast a shadow, much like what that other object appears to do.

On the left side of the pic, about halfway down, is that Tethys I see? Or am I imagining things?
