Welcome to Disko Bay near the town of Ilulissat, Greenland, where summer"s midnight sun will dip just below the horizon for only about an hour and a half tonight. In fact, for several weeks in the period around the summer solstice, the sun doesn"t set at all on Disko Bay. Technically, the "midnight sun" occurs in places north of the Arctic Circle or south of the Antarctic Circle when the sun remains visible at the local midnight. This natural phenomenon lasts from April to August in the northern regions of Greenland. (The opposite effect, polar night, occurs during winter months when the sun does not rise above the horizon.)
