In addition, the best sightings are when there is a large amount of solar activity. Generally, it is held that prime seasons for viewing the northern lights are early autumn and spring. You could see them at any time between September and March but you need to be in the right place.
The Northern Lights, as the name suggests, are especially related to the polar regions. They occur most frequently in a belt of radius 2500 km centered on the magnetic north pole.n Troms and Finnmark, we can see the Northern Lights every other clear night, if not even more frequently. From southern Norway, sightings would be only a few times a month while in central Europe hardly more than a few times a year and they have even been seen from the Mediterranean but only a few times each century.
