Explanation: Want to see a rainbow smile? Look near the zenith (straight up) when the sun is low in the sky and you might. This example of an ice halo known as a circumzenithal arc was captured above a palm tree top from Ragusa, Sicily on February 24. The vividly colorful arcs are often called smiling rainbows because of their upside down curvature and colors. For circumzenithal arcs the zenith is at the center and red is on the outside, compared to rainbows whose arcs bend toward the horizon after a downpour. True rainbows are formed by water droplets refracting the sunlight to produce a spectrum of colors, though. Circumzenithal arcs are the product of refraction and reflection in flat hexagonal ice crystals, like the ice crystals that create sundogs, formed in high thin clouds.

I used to see them in the UK. That’s what they called them.

Love your tagline.

I prefer the Neuman U87 though. :-)

Oooooh! Where's my Aunt Bethany face? :)

Reminds me of

Mark 13:25-26 And the stars of heaven shall fall, and the powers that are in heaven shall be shaken. 26 And then shall they see the Son of man coming in the clouds with great power and glory.

After all, a rainbow has a name: Roy G. Biv

He must be Irish!

I once saw a circular rainbow - a total circle.

It appeared around us as our 6 man formation entered a cloud at 9,000 feet, ten of us were in freefall getting in the formation.

It truly was one of the most beautiful sights I have ever seen. The cloud lasted about four or five seconds.

Suddenly we exited the cloud and reality smacked us in the face. Going from white to reality and ground rush does smack you.

The cloud busting was unintentional. All of us didn’t care. We were so jazzed at that jump we talked about it for months.
