Where Will the Moon Be Tomorrow?

This is a ConcepTest I ask in class (or Think/Pair/Share, or whatever your favorite name for interactive multiple-choice questions asked of studnets during lectures). I've told them howe everything, as viewed looking "down" on the plane of the orbits, goes counter-clockwise. Given that the moon is orbiting counter-clockwise about the Earth, if they can properly visualize the motions they should be able to answer the qestion below. I demonstrate the ansewr with a movie.

You see the moon high in the southen sky one night, as shown to the right. Where will you see the moon at the same time tomorrow?
