Richard Carrington
Richard Christopher Carrington (26 May 1826 – 27 November 1875) was an English amateur astronomer whose 1859 astronomical observations demonstrated the existence of solar flares as well as suggesting their electrical influence upon the Earth and its aurorae; and whose 1863 records of sunspot observations revealed the differential rotation of the Sun. Life Carrington was born at Chelsea, the second son of Richard Carrington, the proprietor of a large brewery at Brentford, and his wife Esther Clarke Aplin. He entered Trinity College, Cambridge, in 1844; but, though destined for the church, rather by his father's than by his own desire, his scientific tendencies gradually prevailed, and received a final impulse towards practical astronomy from Professor Challis's lectures on the subject. This change in the purpose of his life was unopposed, and he had the prospect of ample means; so that it was purely with the object of gaining experience that he applied, shortly after taking ...

Chelsea, London
Chelsea is an affluent area in west London, England, due south-west of Charing Cross by approximately 2.5 miles. It lies on the north bank of the River Thames and for postal purposes is part of the south-western postal area. Chelsea historically formed a manor and parish in the Ossulstone hundred of Middlesex, which became the Metropolitan Borough of Chelsea in 1900. It merged with the Metropolitan Borough of Kensington, forming the Royal Borough of Kensington and Chelsea upon the creation of Greater London in 1965. The exclusivity of Chelsea as a result of its high property prices historically resulted in the coining of the term "Sloane Ranger" in the 1970s to describe some of its residents, and some of those of nearby areas. Chelsea is home to one of the largest communities of Americans living outside the United States, with 6.53% of Chelsea residents having been born in the U.S. History Early history The word ''Chelsea'' (also formerly ''Chelceth'', ''Chelchith' ...

James Challis
James Challis FRS (12 December 1803 – 3 December 1882) was an English clergyman, physicist and astronomer. Plumian Professor of Astronomy and Experimental Philosophy and the director of the Cambridge Observatory, he investigated a wide range of physical phenomena though made few lasting contributions outside astronomy. He is best remembered for his missed opportunity to discover the planet Neptune in 1846. Early life Challis was born in Braintree, Essex where his father, John Challis, was a stonemason. After attending various local schools, he graduated from Trinity College, Cambridge in 1825 as Senior Wrangler and first Smith's prizeman. He was elected a fellow of Trinity in 1826 and was ordained in 1830. He held the benefice of Papworth Everard, Cambridgeshire from the college until 1852. In 1831 Challis married Sarah Copsey, ''née'' Chandler, a widow, and consequently resigned his Trinity fellowship. The couple had a son and a daughter.Clerke (2006) Plumian professor ...

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

Solar Eclipse Of September 7, 1858
A total solar eclipse occurred on September 7, 1858. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. It was visible across South America.

Lilla Edet
Lilla Edet is a locality and the seat of Lilla Edet Municipality in Västra Götaland County, Sweden. It had 4,862 inhabitants in 2010. Lilla Edet was the smallest of three settlements that were burnt down in Sweden on 25 June 1888. The wooden towns of Sundsvall and Umeå were almost completely destroyed. The triple fire was widely reported and one collection in California raised $5,000 and blankets and tents were sent from New Zealand. The town Lilla Edet is situated on the eastern side of the Göta älv, a main river on the west coast of Sweden. It became known as a halt there. The area was known locally as Lilla Edet in comparison to Stora Edet, situated north of Lilla Edet and today known as Trollhättan. However, for a long time the official name of Lilla Edet was Bergaström.

Circumpolar Stars
A circumpolar star is a star that, as viewed from a given latitude on Earth, never sets below the horizon due to its apparent proximity to one of the celestial poles. Circumpolar stars are therefore visible from said location toward the nearest pole for the entire night on every night of the year (and would be continuously visible throughout the day too, were they not overwhelmed by the Sun's glare). Others are called ''seasonal'' stars. All circumpolar stars lie within a circumpolar circle whose size is determined by the observer's latitude. Specifically, the angular measure of the radius of this circle equals the observer's latitude. The closer the observer is to the North or South Pole, the larger the circumpolar circle is. Before the definition of the Arctic was formalized as the region north of the Arctic Circle which experiences the Midnight sun, it more broadly meant those places where the 'bear' constellations (Ursa Major, the Great Bear, and Ursa Minor, the Little Bear) ...

Equatorial Mount
An equatorial mount is a mount for instruments that compensates for Earth's rotation by having one rotational axis, the polar axis, parallel to the Earth's axis of rotation. This type of mount is used for astronomical telescopes and cameras. The advantage of an equatorial mount lies in its ability to allow the instrument attached to it to stay fixed on any celestial object with diurnal motion by driving one axis at a constant speed. Such an arrangement is called a sidereal or clock drive. Equatorial mounts achieve this by aligning their rotational axis with the Earth, a process known as polar alignment. Astronomical telescope mounts In astronomical telescope mounts, the equatorial axis (the '' right ascension'') is paired with a second perpendicular axis of motion (known as the '' declination''). The equatorial axis of the mount is often equipped with a motorized "''clock drive''", that rotates that axis one revolution every 23 hours and 56 minutes in exact sync with the appar ...
