The Midnight Sun

eclipse

The midnight Sun shines over Lake Colleen at Deadhorse (Prudhoe Bay), Alaska, on July 7, 2007. The Sun is still so far north that it stays up for 24 hours a day, which is possible only above the Arctic Circle. It will finally set later in the month as it moves to the south. A latitude here of 70.2 degreees north gives an actual solar (center) elevation of 2.8 degrees, which is raised to 2.9 degrees by atmospheric refraction.
