I went out and observed the dark side of the moon for awhile to count the number of Leonids hitting the moon - as if there would be any :-) It became obvious that without previous experience it would be impossible to recognize an impact from the flashes that once in awhile occurs in my eyes, probably as the vitreuos fluid pulls on the back of my eyeball. I did observe one interesting thing. There was a part of the moon that persistently produced flashes. It was centered at a small point like, but still extended, area that was lighter than the rest of the dark side of the moon. My guess is that when I was looking at the rest of the dark moon (the sunlit part was outside the field of view), this area is in my averted vision, and once in awhile the brighter spot on the moon stimulated a sensitive rod, causing what appeared to be a flash.
