Moon 28th December 2017

Two photos, one hour apart, and the Moon appears to have rotated nearly 20 degrees clockwise.

But this is an optical illusion. The reason it appears to have rotated is because we look at the moon at different angles! This is because both the Earth and Moon are rotating anti-clockwise but the Moon rotates about 30 times slower.

Here is a video that may help!
