Multiple Moon Halos

I was just wandering back to my apartment, and I looked up at the moon...and saw this. Well, a much better version, actually, but by the time I realized what I was looking at, ran up to my apartment, scattered the stuff I was carrying, frantically searched for and grabbed my camera/tripod, and had everything set up, the halos were fading.

To the right is the familiar parhelia (more widely known as sundogs), though they're called paraselenae/parselenae when created by the moon instead of the sun, with a tiny bit of a 22-degree halo and a parselenic circle (don't know if that's the right term--it's the moon version of a parhelic circle). But above the trees can be seen an upper tangent arc, which I haven't even seen the sun do, let alone the moon.

It was an amazing sight. (I'm sure my fellow apartment-dwellers think I'm crazy.) It sure got my heart racing. I know 22-degree moon halos and parselenae can happen somewhat frequently, but I don't know about upper tangent arcs. The atmospheric optics site I frequent doesn't say anything about them.

Don't see what I'm talking about? Try this image: 1) 22-degree halo, 2) parselene, 3) parselenic circle, 4) upper tangent arc.
