When the moon is directly between the Earth and the Sun in roughly a month's time (April 18th) a camera on the moon would register a surface rotation of roughly 30 degrees using the fully illuminated face and the North pole as a gauge, the next sweep will be roughly another 30 degrees so that when the moon is between the Earth and the Sun around the June Solstice, the entire planet's surface will have turned 90 degrees,again,using the poles as a gauge. This surface rotation is already seen within the solar system.
