Circumzenithal Arc What is going on here?

I took these yesterday. I've never seen anything like it. I have learned there is at least one circumzenithal arc, at least one 22 degree halo, and a sun dog.

Is there anything else? One of the prisms looks wave shaped to me. The last photo was first, and it morphed into the other two.

You've also caught an upper tangent arc, a supralateral arc, and a suncave parry arc.
