The Midnight Sun stays above the horizon, and it is light 24 hours a day. The sky must be clear and there must be unobstructed visibility northwards in order to see the Midnight Sun. A summer night on the fjord or in the mountains is an experience not to be missed, you can go fishing in the fjord, which contains splendid variation of fish, or you can take a walk in the wilderness surrounding.
Aurora Borealis is the Latin name for the Northern Lights – solar winds that meet the atmosphere in a zone around the magnetic North Pole. The Northern Lights are only visible when the sky is dark and clear, from August to April, and they are most intense from 10 pm to midnight. The region on the 700 northern latitude is a fantastic place for experiencing the beautiful and intense play of colours given off by the Northern Lights.
The dark time, or the long, dark Polar Night, lasts from 30th November - 12th January - there is only a twilight-dusk type of light (the blue light) for a few hours during the middle of the day. This does not mean that it becomes totally dark, however. The aurora borealis trails its multicoloured banner across the sky and the moon lights the scene just like the nightlight of Our Lord. The experience of the winter with the uniqueness of the light, the northern lights and snow is fantastic. Especially beautiful is the blue light southwards, just before it becomes dark.
