Yup. It also gets down to -40 in the winter.

  I'm less surprised about that. Land climate and no warm gulf stream makes for a totally different climate. But I didn't expect the northern lights to be ruled by temperature.

    I think it is more ruled by the earth magnetic field. And as the magnetic pole is closer to north america, you have them further (geographically) south there.

      That's a lot more likely. Magnetic North is 80 degrees north rather than 90, and in Canada, so if you can see the northern lights at 50 degrees there, that would be comparable to 60 or 70 degrees elsewhere.

        Patall is right, I was just pointing out another surprising winter-related fact. But it's not surprising if you understand weather systems.
