Here's why:

* Earth's Magnetic Field: The Aurora Borealis is caused by charged particles from the sun interacting with Earth's magnetic field. This magnetic field is strongest near the Earth's poles.

* Auroral Ovals: The areas where the auroras are most commonly seen are called auroral ovals, which are located around the magnetic poles. The northern auroral oval is centered around the North Magnetic Pole, which is located in the Arctic region.

While the Aurora Borealis is primarily a northern phenomenon, there is also an Aurora Australis, which is seen in the Southern Hemisphere near the South Magnetic Pole.
