There was a ... I want to call it a sliver of a rainbow? But I guess it was like a halo or something.
But there were two rainbow-y stripes in the sky that were not connected, and were backwards (red on the right, green/blue/violet on the left)
It was neat. I don't think I've seen that before.
@ajroach42 my first thought upon reading this was "oooh, sundogs?" but it might've been something else in the "ice halo" bucket – still neat regardless!
