A spaceweather.com reader in Denmark uploaded a nice picture of green aurora just above the horizon.

Basically the sun emits particles that travel towards the planets. These particles get deflected by Earth's magnetic field. When they get deflected they move towards the weakest points on said magnetic field, which happens to be the north magnetic pole, and south magnetic pole. When they get low enough into the atmosphere they interact with they air causing the colors.
