Had one goofy "stars" incident years ago. Flying over North Dakota at night. A lot of the farms have one white street lamp type light on the barn. Those combined with the stars combined to make the optical illusion that we were surrounded by stars, both above and below.

Since the oil patch boom up there, the phenomena is gone, replaced by the gas fire burnoffs from the oil wells, but it was cool at the time.

I've also seen the International Space Station reflecting sunlight out over the Pacific a couple times as well.

However, nothing compares with a good Aurora Borealis light show.
