phenomenon occurring in latitudes north to the
Arctic Circle and south and nearby to the north of the Antarctic
Circle where the sun remains visible at the local midnight.
Given fair weather, the sun is visible for a continuous 24
hours. The number of days per year with potential midnight sun
increases the further north of the Arctic Circle or south of the
Antarctic Circle one goes.
The Arctic Circle in North Norway is located close to the Arctic town of Bodo and south of the Lofoten Islands.
South of the Arctic Circle in Norway the nights are bright ("white") as well during spring/early summer due to the altitude, although the sun is not visible all night
