NOT A RAINBOW

I went into the back yard after dinner to see whether the moon was visible and saw this instead. As far as I can find out, it's a circumhorizontal arc and not a proper rainbow, so it doesn't matter that it's too early to tag it for the Blip Community June Rainbow Challenge. I was lucky to get a crow (I think) and a plane (bottom right corner) flying over at the same time.

I'm not surprised there were ice crystals up there - it was about 10 degrees cooler today than yesterday.

Edit: Sister A1 tells me she's seeing FB posts of this phenomenon from all over northern England and southern Scotland, and she's seen multiple arcs bouncing off each other, which sounds much more spectacular than this!
