The 50th parallel north is a circle of latitude that is 50 degrees north of the Earth's equatorial plane. It crosses Europe, Asia, the Pacific Ocean, North America, and the Atlantic Ocean.
At this latitude the sun is visible for 16 hours, 22 minutes during the summer solstice and 8 hours, 4 minutes during the winter solstice.[1] The maximum altitude of the sun during the summer solstice is 63.44 degrees and during the winter solstice it is 16.56 degrees. During the summer solstice, nighttime does not get beyond astronomical twilight, a condition which lasts throughout the month of June. It is possible to view both astronomical dawn and dusk every day of the month of May.[2]
At this latitude, the average sea surface temperature between 1982 and 2011 was about 8.5 °C (47.3 °F).[3]

Sakhalin island
From the signing of the 1875 Treaty of Saint Petersburg until the Russo-Japanese War which broke in 1904, the Russian Empire had full control of Sakhalin island. As a result of the 1905 Treaty of Portsmouth that brought an end to the Russo-Japanese War, the portion of the island south of the 50th parallel line became Japanese territory, part of Karafuto Prefecture. However, following the month long Soviet–Japanese War during the summer of 1945, the entire island was reunified under Soviet control.[4]
