In the northern hemisphere, in which direction should a directional antenna be pointed to take maximum advantage of auroral propagation?

Auroral propagation utilizes the highly ionized curtains of the Aurora Borealis (Northern Lights) as a massive reflector for VHF and UHF radio signals. In the northern hemisphere, this auroral activity is concentrated around the North magnetic pole. To bounce a signal off this ionized region and reach another station, both operators must point their highly directional antennas North toward the aurora itself. This means you do not point your antenna directly at the station you want to communicate with, but rather use the Northern sky as a shared reflective surface.
