If you're chasing the northern lights I recommend staying at least a week. It has to be very cold i.e. no clouds, very clear skies for the lights to be seen. So it's all dependent on the weather. Some people have stayed for a week and did not manage to get to see the lights. To get to see the lights you have to go up as north as possible, that is why Tromso in Norway is one of the best places to see them as you're in the arctic circle.
thanks for the info! shall make adjustments to my trip.
