Each and every one of those pics is evidence of the governmental-reptoid conspiracy to cover us all in toxic chemtrails. THE TRUTH IS OUT THERE!

This is one fine example of why my friends have sometimes made fun of me for always looking at the sky whenever we're walking around. Well not because of the rainbows but because I'm always craning my neck up. I love what the sky has to offer, day and night. Thanks for showing me a couple that I've not heard of before. (elliptical halo and reflected rainbows)

Double but the site moved.

Cool - thanks for posting this! Here's another neat atmospheric optical mystery, via APOD, yesterday.

Gravity waves create banded airglow!? That's fucking awesome!!!!!

No thread about atmospheric optics (especially one that already has the obligatory paranoia comment in it) would be complete without

Rainbow in my Sprinkler (it's not a euphemism, it's a YouTube)

Very nice site. Some of these phenomena can be very cool to see in person. I've seen some incredibly bright sundogs while skiing at Whistler, and an amazing double rainbow at Burning Man '07. Both of those were pretty impressive optical phenomena that I won't soon forget.

No rainbowpuke?

Stonestock Relentless, beware mixing gravity waves with gravitational waves.

Rhomboid, your first link made me wary of the others.

Yeah...I think the picture from that first link Rhomboid posted must be photoshopped or something. That rainbow isn't possible, unless maybe there's a powerful light source behind the camera on the ground.

Ah, my apologies! It is not photoshopped - it is instead a circumzenithal arc, which results from refraction through ice crystals instead of water droplets, thus the strange position and angle in the sky. Neat - you learn something every day.

And I see now that f.t.'s comment referred to the puking rainbows link. Goodnight.

If you like these links, you should check out this book.

This is a great post - I really like the little 3-D renderings explaining each process. Awesome find.

The geometry and simple beauty of nature is positively astonishing.

And I got your unicorn right here, buddy.
