I saw something tonight I've never seen before. In fact, I'd only heard of it once, a long time ago, and had forgotten until I saw it tonight.

It was a bright, white (to my eyes) moonbow

They're pretty rare, especially in these parts, with as little rain as we have, but it just happened to be raining in the very right spot.

Quite lovely and subtle and, beyond what I've said, difficult to give it justice in words.
