The impressive glory was photographed during a flight from Prague to Athens, on December 18, 2014. We were flying just above a stratocumulus or an altocumulus cloud deck. The glory's color is similar to that of the rainbow, but cloud droplets interacting with sunlight (diffraction and Mie scattering) rather than raindrops cause the concentric rings of light. However, with both rainbows and glories, the Sun must be behind the viewer (antisolar point) in order to see these phenomena.
