      Northern Lights active in the U.P.

      The higher latitudes of Upper Michigan make it a great place to try and see the Northern Lights.

      The spectacular light show is caused by the interaction between sun particles and upper atmosphere particles. When these are released on the Earth's magnetic field, lots of energy is produced.

      If we happen to be in right direction, it means we'll get to see the Northern Lights.

      While the past few years haven't been great for seeing the Northern Lights, scientists believe we may be heading into an active period.

      "For many years now it's been very inactive. There have been very few sunspots to see," said NMU's Head of Physics David Lucas. "The other day or a few weeks ago, we looked and there was some sunspot activity beginning, and so I think it's coming back up. We're into a more active phase."

      The colors seen in the light show depend on how much oxygen and nitrogen is present, but usually observers will see mostly green and red.
