I missed the meteor this week, but at least got to see a combined atmospheric phenomenon this morning at the beach.

Close, but this is in fact the circumhorizontal arc. It's very similar to the cza, but the refractions happen in the opposite order. The cha occurs below the sun when the sun is high, the cza occurs high above the sun (near the zenith) when the sun is low.

Nice pictures!

Ah thanks! Now I'm wondering if that 22° halo was really a circumscribed arc.
