A Solar Optics Rainbow Cloud

Earlier today, I saw this cloud in the sky to the south that was lit up like a rainbow from the glancing rays of sunlight. It was an amazing little puff of rainbow color floating high in the sky. I grabbed my camera and got this image. Click on the image to enlarge.

From EarthSky:

These colorful clouds are called iridescent clouds, and the phenomenon is called cloud iridescence or irisation. The term comes from Iris, the Greek personification of the rainbow. It’s similar to the colors you might see when oil lies on the surface of a puddle of water. When you see a cloud like this, you know there are especially tiny ice crystals or water droplets in the air. Larger ice crystals produce solar or lunar halos, but tiny ice crystals or water droplets cause light to be diffracted – spread out – creating this rainbow-like effect in the clouds.
