Glories
A glory is produced by a process similar to rainbows, but with a part of the light that takes a different set of angles of diffraction, reflection, and refraction as it passes through water droplets. The angle of a glory from the light source is much smaller than a rainbow. The colors appear in a spread of about 5o to 20o. Glories are often associated with another optical effect, spectre of the brocken.
Your shadow will always appear to be in the center of the Glory..
