I just saw the article about Iridescent cloud?
Or circumhorizon arc? June 9th and I couldn’t get my photo’s to load on the discussion so I thought I would put them here. There were a lot of weird contrails in the sky the other morning June 6 and I noticed the “rainbow” in the clouds so I took some pics. So not sure if Iridescent or Circumhorizon. Also will load one more pic but I guess you can only put one at a time here.
