In higher latitudes that's a common effect known as iridescence.

Interesting article, in part because I have been researching the circumhorizon arc myself. July 12th I got these photos as we were driving toward southwestern Missouri around 12pm.

From what I've learned, the higher halo is a 22 degree halo (although I'm still confused as to the difference between 22 and 46 degree halos). It's hard to tell on the photos, but there are actually 2 bands on the higher ring, one being more ovalish and the other being round (the 22 degree halo). From what I've read, the ovalish halo might be considered as a circumscribed halo?
Then, of course, the lower band would be a circumhorizon arc.

If anyone has more information about these, I would really appreciate it.
