Phases of the moon are simply how much sun is hitting the surface of the moon, with the moon being between the earth and the sun. Lunar eclipses occur when a conjunction between the earth and the sun... with the earth casting a shadow on the full moon.

You usually won't notice any difference in the moon's light at this point. This stage will last for about thirty minutes.
