Optical Glory

One of the best ways to see a glory is from an aircraft overflying liquid-water clouds. Sunlight is backscattered toward the sun by uniformly sized cloud droplets, in a process loosely akin to the visualization of a rainbow (but with far smaller water particles). When observing a true glory, your eyes always will lie on a straight line between its middle and the sun behind you. Put another way--when on a high bridge, skyscraper, airplane or mountain, look directly opposite the sun to spot any glory that might appear from clouds below.
