Editor’s Note: When EarthSky first published this image, we misidentified it as a photo of iridescent clouds. In fact, it’s a circumhorizon arc. Mistaking one for the other is easy, but here are some tricks that can help. Our thanks to alert reader George Preoteasa for pointing out the mistake … and apologizes for any confusion!
