60th parallel north

The 60th parallel north is a circle of latitude that is 60 degrees north of Earth's equator. It crosses Europe, Asia, the Pacific Ocean, North America, and the Atlantic Ocean. Although it lies approximately twice as far away from the Equator as from the North Pole, the 60th parallel is half as long as the Equator line, due to the cosine of 60 degrees being 0.5. That is, a point on Earth’s surface at this latitude is half as far from the rotational axis as a point on the Equator is. At this latitude, the Sun is visible for 18 hours, 7 minutes during the June solstice and 5 hours, 52 minutes during the December solstice. The maximum altitude of the Sun is 53.44° on 21 June and 6.56° on 21 December. The maximum altitude of the Sun is > 15.00º in October and > 8.00º in November. The lowest latitude where white nights can be observed is approximately on this parallel. White nights in the 60th parallel north occur around the June Solstice (Summer Solstice in the Northern Hemisphere). During the summer solstice, nighttime does not get beyond nautical twilight, a condition which lasts throughout the month of June. It is possible to view both astronomical dawn and dusk every day between August 22 and April 21.
