Q:

Finding north without a compass

At night, someone is in a completely empty field. He sees absolutely nothing around him and there are no stars in the sky. He does not have a compass, or any other tools that can be used for navigation, and the only think he knows about the time is that it's before midnight. He's been there for less than a minute, but he already knows which way is north. 
How did he know?

Even though this answer got accepted: This answer will not really work and it is not 100% correct. Thanks to Peter Taylor and Anachor for catching that. I would be interested if there is a better answer (there surely is).

 Becuase it's before midnight, the illuminated side of the moon faces west. (After midnight it's east). Now just face west and turn right - Then you face north.
