Lunar Corona
A broken, diffuse altocumulus deck put on a colorful show of nocturnal atmospheric optics during the cool, pre-dawn hours. Coronas come to the eye by means of optical diffraction (bending of light) through small water droplets of the clouds. I enjoyed this corona more than most because the cloud layer moving quickly and was nonuniform—in fact, quite chunky—imparting some welcome, ever-changing texture to the scene.
