Have You Seen the Lunar X?

Nothing is so special about the Lunar X. You probably won't see it by just looking at the moon tonight. You can see it through a telescope, but only during certain phases of the moon. The Lunar X is a sort of an optical feature formed when the sun shines on the craters of the moon from a very low angle. The lit parts of the craters and the shadows form an X as you can see in the photo below.
