The 49th parallel north is a circle of latitude that is 49° north of Earth's equator. It crosses Europe, Asia, the Pacific Ocean, North America, and the Atlantic Ocean. The city of Paris is about 15 kilometres (9 miles) south of the 49th parallel and is the largest city between the 48th and 49th parallels. Its main airport, Charles de Gaulle Airport, lies on the 49th parallel. Roughly 2,030 kilometres (1,260 miles) of the Canada–United States border was designated to follow the 49th parallel from British Columbia to Manitoba on the Canada side, and from Washington to Minnesota on the U.S. side, more specifically from the Strait of Georgia to the Lake of the Woods. This international border was specified in the Anglo-American Convention of 1818 and the Oregon Treaty of 1846, though survey markers placed in the 19th century cause the border to deviate from the 49th parallel by up to 810 metres (0.503 miles). From a point on the ground at this latitude, the sun is above the horizon for 16 hours, 12 minutes during the summer solstice and 8 hours, 14 minutes during the winter solstice. This latitude also roughly corresponds to the minimum latitude in which astronomical twilight can last all night near the summer solstice. All-night astronomical twilight lasts about from June 9 to July 2. At midnight on the summer solstice, the altitude of the sun is about −17.56°. Slightly less than one-eighth of the Earth's surface is north of the 49th parallel.
