This means that you will see the Northern Lights quite regularly if you live near the arctic circle (or the Antarctic circle) and increasingly more rarely the closer you get to the Equator.
This phenomenon is caused by solar particles that get deflected by our magnetic field towards the Poles. The stronger the solar storm that hits us, the lower the particles hit the atmosphere latitude-wise. This means that you will see the Northern Lights quite regularly if you live near the arctic circle (or the Antarctic circle) and increasingly more rarely the closer you get to the Equator.
