The clouds and the rainbow work perfectly together. And the trees off to the side are perfect.

(152,301 posts)I especially like the way you brought out the texture in the clouds. They are just exquisite. And the iridescence! Wow.

(3,411 posts)It was in month of October, near Erie, PA. The DJ on the radio station I was listening to made mention of it. He then played a few moon-themed songs.
I think the ring phenomenon happens mostly at or near the full phase of the moon. I think that I read that it has to do with ice crystals in the earth's upper atmosphere. I think that, when the phenomenon occurs, the distance from the moon to the ring (as viewed from our vantage point on earth) is always the same.

(5,349 posts)but recall only a few times when the iridescence was so striking.
The shape of these ice crystals focuses light into a halo around the moon or the sun. As ice crystals are usually hexagonal these lunar halos are almost always the same size, with the moon (or the sun) sitting 22 degrees from the other edge of the halo roughly the width of an outstretched hand at arm's length.
The uniform 22-degree radius and 44-degree diameter of halos mean that both solar and lunar halos are often referred to as 22-degree halos.
This uniformity in diameter arises because ice has a specific index of reflection and the hexagonal shape of an ice crystal means when its sides are extended it forms a prism with a 60 -degree apex angle. This results in an angle of minimum deviation for light passing through the ice crystal of 21.84 degrees.
These ice crystals also demonstrate a prism effect that separates white light from the sun or is reflected by the moon into various individual colors just like the atmospheric effect that creates a rainbow.
