Christmas CZA

I got treated with a beautiful CZA on Christmas.

  1. CZA's are probably my favourite of all atmospheric phenomena. For some reason, the ones I like best are where the blue, indigo and violet are very prominent. Those colours don't normally stand out too well against the background blue, but when they do they shimmer like jewels in the sky.

  2. I think CZA's might even be more lovely than CHA's. Circumhorizon arcs do not have that beautiful smile shape that the CZA does. However, they do come second in my opinion!
