Pair that up with a lunar eclipse, and you will have a spectacular view of the moon turning dark as it moves out of the sun's light and into the shadow of the Earth. Only the light reflected off Earth will be visible on its surface, producing a ruddy red-brown color on the moon's surface during totality.
