With a little sun and a little rain I of course looked up at the sky (opposite the sun) looking for a rainbow, which wasn’t there. So I started turning slowly in a circle--there had to be rainbow somewhere. And then we saw it, something we’d never seen before: a rainbow in the same part of the sky as the sun, and upside down! We later learned that it’s called a “circumzenithal arc.” We have a couple of pictures here of the one that we saw, but you can find plenty of others on the internet.
