A GLORY is a delightful phenomenon formed when light is scattered backwards by individual water droplets. The light source usually is the sun.  Glories are visible directly opposite the sun, centered at the antisolar point below the horizon except at sunrise and sunset.  While an observer’s shadow plays no role in the phenomenon, it provides an easy way to find the antisolar point.  This is because shadows converge on the antisolar point, therefore, glories typically accompanied by your shadow or that of the aircraft you are in.

Mountain climbers and folks in aircraft see glories.

When the shadow itself is oddly distorted by perspective it is called a "Brocken spectre".

The image here is that of a brocken spectre taken in NE England by photographer Vincent Lowe (shown w/permission) in February 2006.  Wiki Hopegill Head for a look at this beautiful ‘fell’.
