And now for something completely different

Has anyone else noticed the Heiligenschein effect?  I “discovered” this a couple of years ago, and sometimes entertain myself on long flights trying to find it. On sunny days, look for where your shadow should fall, and you may see a slightly brighter patch of ground.  Some objects such as street signs will glow brightly for a few seconds when  this zone passes over them. It’s a phenomenon similar to the “glory”, I think. Everything I’ve read about this relate it to reflection off of water droplets, but I’ve seen it on days when it’s dry.  As I said, something completely different.
