The "Heiligenschein" or "Holy Light" manifests itself as a glow around the head of an observer in the direction opposite the sun (the anti-solar point.)

It is best observed when the grass is wet with dew and the shadows are long. I finally got some good images yesterday morning at Lakehurst (click on them to bigafy to better see the glow effect).

The dew drops focus the incoming light onto the grass which is then reflected back through the drop in the direction it came. Thus I, and you via these images, can see a brightening around the shadow of my head.

Wow, that shadow makes my butt look big.

I held the camera away from me and you can see that the glow is now around shadow of the camera. Thus, as with rainbows, each observer has their own personal halo.

More info can be found here. But you knew that already, right?
