Circles of latitude between the 45th parallel north and the 50th parallel north
Following are circles of latitude between the 45th parallel north and the 50th parallel north:
46th parallel north
The 46th parallel north is a circle of latitude that is 46 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 15 hours, 45 minutes during the summer solstice and 8 hours, 38 minutes during the winter solstice.
Around the world
Starting at the Prime Meridian and heading eastwards, the parallel 46° north passes through:47th parallel north
The 47th parallel north is a circle of latitude that is 47 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 15 hours, 54 minutes during the summer solstice and 8 hours, 31 minutes during the winter solstice. This is the northern limit of the visibility of the star θ Scorpii and thus of the 'tail' of the constellation Scorpius.
Around the world
Starting at the Prime Meridian and heading eastwards, the parallel 47° north passes through:48th parallel north
The 48th parallel north is a circle of latitude that is 48 degrees north of the Earth's equatorial plane. It crosses Europe, Asia, the Pacific Ocean, North America, and the Atlantic Ocean.In Canada the parallel forms part of the border between Quebec and New Brunswick.
Ships heading north along the coast of Washington toward the Strait of Juan de Fuca must make radio contact with Canadian Coast Guard vessel traffic service upon crossing the 48th parallel.
At this latitude the sun is visible for 16 hours, 3 minutes during the summer solstice and 8 hours, 22 minutes during the winter solstice. If the latitude in the northern hemisphere is 48º50' or smaller, it is possible to view both astronomical dawn and dusk every day of the month of July. At the latitude of 48°33′38.58804” North, which is about 62.3 km north of this parallel, is the parallel where twilight/nighttime boundary on the June Solstice.
Around the world
Starting at the Prime Meridian and heading eastwards, the parallel 48° north passes through:49th parallel north
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 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 parallel.
Roughly 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.
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 from about June 9th to July 2nd. 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.
Around the world
Starting at the Prime Meridian and heading eastwards, the parallel 49° north passes through:Ordnance Survey of Great Britain
The British national grid reference system uses the point 49° N, 2° W as its true origin.50th parallel north
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.
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.
At this latitude, the average sea surface temperature between 1982 and 2011 was about 8.5 °C.
