Starting at the Prime Meridian and heading eastwards, the Arctic Circle passes through:

Nevertheless, the line in the old observatory's courtyard today differs no more than a few metres from that imaginary line which is now the Prime Meridian of the world.

A longitude describes the location of a place on Earth east or west of a north-south line called the Prime Meridian.

Longitude is given as an angular measurement ranging from 0 ° at the Prime Meridian to + 180 ° eastward and − 180 ° westward.

By convention, one of these, the Prime Meridian, which passes through the Royal Observatory, Greenwich, England, establishes the position of zero degrees longitude.

The longitude of other places is measured as an angle east or west from the Prime Meridian, ranging from 0 ° at the Prime Meridian to + 180 ° eastward and − 180 ° westward.

Specifically, it is the angle between a plane containing the Prime Meridian and a plane containing the North Pole, South Pole and the location in question.

This forms a right-handed coordinate system with the z axis ( right hand thumb ) pointing from the Earth's center toward the North Pole and the x axis ( right hand index finger ) extending from Earth's center through the equator at the Prime Meridian.

In 1884, the International Meridian Conference adopted the Greenwich meridian as the universal Prime Meridian or zero point of longitude.

Longitude is given as an angular measurement ranging from 0 ° at the Prime Meridian to + 180 ° eastward and − 180 ° westward.

The Greek letter λ ( lambda ), is used to denote the location of a place on Earth east or west of the Prime Meridian.

The location of the Prime Meridian as well as the position of body's north pole on the celestial sphere may vary with time due to precession of the axis of rotation of the planet ( or satellite ).

If the position angle of the body's Prime Meridian increases with time, the body has a direct ( or prograde ) rotation ; otherwise the rotation is said to be retrograde.

Senegal is a coastal West African nation located 14 degrees north of the Equator and 14 degrees west of the Prime Meridian.

The Royal Greenwich Observatory, in South East London, is the defining point of the Prime Meridian.

* 1884: International Meridian Conference in Washington D. C., held to determine the Prime Meridian of the world.

The Prime Meridian passes the western edge of the Dome and the nearest London Underground station is North Greenwich on the Jubilee Line.

The principal meridian of that observatory was chosen in 1884 by the International Meridian Conference to be the Prime Meridian.

It is a modern continuation of Greenwich Mean Time ( GMT ), i. e., the mean solar time on the Prime Meridian at Greenwich, and GMT is sometimes used loosely as a synonym for UTC.

The projected union initially aroused great opposition: he did not consult with his father, who had been on vacation in Karlovy Vary and making arrangements to secure the hand of a German princess for his son, or his Prime Minister Dr. Vladan Đorđević, who was visiting the Paris Universal Exhibition at the time of the announcement.

Clinton brought Israeli Prime Minister Ehud Barak and Palestinian Authority Chairman Yasser Arafat together at Camp David.

However, most of this aid has been targeted at the Federation ; the previous government of the RS was anti-Dayton and not assisted by the U. S. The election of the " Sloga " or " Unity " Coalition government, led by Prime Minister Dodik, has shifted the balance of power in the Republika Srpska ( RS ) to a pro-Dayton stance and will result in an upsurge of funding to the RS from the international community.

He had stabilised the Allied position at the First Battle of El Alamein, but after a visit in August 1942, the Prime Minister, Winston Churchill, replaced him as C-in-C with Alexander and William Gott as commander of the Eighth Army in the Western Desert.

Although his father had him baptised to Anglicanism at age 12, he was nonetheless Britain's first and thus far only Jewish Prime Minister.

After a decade as president of the Australian Council of Trade Unions, he entered parliament as a Labor MP at the 1980 federal election and became Prime Minister within three years, leading Labor to victory at four consecutive federal elections: 1983, 1984, 1987 and 1990.

This coalition fell apart at the end of 1916, when the Conservatives withdrew their support from Asquith and gave it to Lloyd George instead, who became Prime Minister at the head of a coalition government largely made up of Conservatives.

On 25 May 2006, the then British Deputy Prime Minister John Prescott was photographed by The Mail on Sunday playing croquet at his official residence, Dorneywood.

After meeting with the Japanese Prime Minister, Eisaku Sato, Whitlam observed that the reason Japan at that time was hesitant to withdraw recognition from the Nationalist government was " the presence of a treaty between the Japanese government and that of Chiang Kai-shek ".

However, the majority of the important decisions are held not in the main meetings themselves, but at the informal ' retreats ': introduced at the second CHOGM, in Ottawa, by Prime Minister of Canada Pierre Trudeau, but reminiscent of the excursions to Chequers or Dorneywood in the days of the Prime Ministers ' Conferences.

In July 1962, a 1. 44 megaton ( 6. 0 PJ ) United States nuclear test in space, above the mid-Pacific Ocean, called the Starfish Prime test, demonstrated to nuclear scientists that the magnitude and effects of a high altitude nuclear explosion were much larger than had been previously calculated.

The 1. 4 Mt total yield 1962 Starfish Prime test had a gamma output of 0. 1 %, hence 1. 4 kt of prompt gamma rays.

This means that although a 10 kiloton weapon has only 0. 7 % of the total energy release of the 1. 44-megaton Starfish Prime test, the EMP will be at least 8 % as powerful.

Since the E1 component of nuclear EMP depends on the prompt gamma ray output, which was only 0. 1 % of yield in Starfish Prime but can be 0. 5 % of yield in pure fission weapons of low yield, a 10 kiloton bomb can easily be 5 x 8 % = 40 % as powerful as the 1. 44 megaton Starfish Prime at producing EMP.

The Conservative Party's 2010 manifesto contained a section on " One World Conservatism "— a commitment to spend 0. 7 % of national income on well-targeted aid — and David Cameron, the current leader of the party and British Prime Minister, named Disraeli as his favourite Conservative.

He sought a federally guaranteed minimum price of $ 0. 70 per bushel, but was rebuffed by Prime Minister R. B. Bennett, who saw the source of the problem as a global oversupply.

An example is the Royal Greenwich Observatory, which is also the source of the Prime Meridian ( longitude 0 ° 0 ' 0 "), and the home of the first marine timekeepers accurate enough to determine longitude ( made by John Harrison ).

The f / 3. 29 Prime focus, used with the WFC, allows an unvignetted field of view of 40 arcminutes ( approximately 0. 3 square degrees ).
