Explanation: What's happening to this cloud? Ice crystals in a distant cirrus cloud are acting like little floating prisms. Known informally as a fire rainbow for its flame-like appearance, a circumhorizon arc appears parallel to the horizon. For a circumhorizontal arc to be visible, the Sun must be at least 58 degrees high in a sky where cirrus clouds present below -- in this case cirrus fibrates. The numerous, flat, hexagonal ice-crystals that compose the cirrus cloud must be aligned horizontally to properly refract sunlight in a collectively similar manner. Therefore, circumhorizontal arcs are somewhat unusual to see. The featured fire rainbow was photographed earlier this month near North Fork Mountain in West Virginia, USA.

I’ll run out in the rain to watch a rainbow, but I’ve never seen one even remotely resembling this gem! Thanks.
To: MtnClimber
Wow! that is really cool!

I wasn’t aware all the recent bad news was depressing me until seeing that rare art from the Almighty’s palette, bringing some cheer back to my heart. Thanks for posting it with your daily astronomy pics.

Oooh, nice. Making a wallpaper out of that one.
To: MtnClimber
Wow. I’ve seen a couple of these, both quite a few years ago, but not with such a well defined “fire” effect. Most impressive!
