Solar Eclipse Of July 30, 1935
During the 20th century, there were 228 solar eclipses of which 78 were Solar eclipse#Types, partial, 73 were annular, 71 were total and 6 were hybrids between total and annular eclipses. Of these, two annular and three total eclipses were non-central, in the sense that the very center (axis) of the Moon's shadow will miss the Earth (for more information see Gamma (eclipse), gamma). In the 20th century, the greatest number of eclipses in one year is five, in 1935, though the years 1917, 1946, 1964, 1982 and 2000 had four eclipses each. One month, July 2000, featured two solar eclipses, on Solar eclipse of July 1, 2000, July 1 and Solar eclipse of July 31, 2000, July 31. The predictions given here are by Fred Espenak of NASA's Goddard Space Flight Center. The longest measured duration in which the Moon completely covered the Sun, known as Solar eclipse#Totality, totality, was during the solar eclipse of June 20, 1955. This total solar eclipse had a maximum duration of 7 minutes an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Magnitude Of Eclipse
The magnitude of eclipse is the fraction of the angular diameter of a celestial body being eclipsed. This applies to all celestial eclipses. The magnitude of a partial or annular solar eclipse is always between 0.0 and 1.0, while the magnitude of a total solar eclipse is always greater than or equal to 1.0, and has a theoretically maximum value of around 1.12. This measure is strictly a ratio of diameters and should not be confused with the covered fraction of the apparent area (disk) of the eclipsed body. Neither should it be confused with the astronomical magnitude scale of apparent brightness. Effect of the magnitude on a solar eclipse The apparent sizes of the Moon and Sun are both approximately 0.5°, or 30', but both vary because the distance between Earth and Moon varies. (The distance between Earth and Sun also varies, but the effect is slight in comparison.) In an annular solar eclipse, the magnitude of the eclipse is the ratio between the apparent angular diamete ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Mauritius
Mauritius was a Crown colony off the southeast coast of Africa. Formerly part of the French colonial empire, British rule in Mauritius was established ''de facto'' with the invasion of Isle de France in November 1810, and ''de jure'' by the subsequent Treaty of Paris. British rule ended on 12 March 1968, when Mauritius became an independent country. History Isle de France, which consisted of Mauritius and some other islands had been under French rule since 1715. However, during the Napoleonic Wars, despite the French naval victory in the Battle of Grand Port on 20–27 August 1810, Mauritius was captured on 3 December 1810 by the British under Commodore Josias Rowley. British possession of the island was confirmed four years later by the Treaty of Paris in 1814. Nonetheless, French institutions, including the Napoleonic Code of law, were maintained, and the French language was still more widely used than English. The British administration, with Robert Townsend Farquh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Réunion
Réunion (; ; ; known as before 1848) is an island in the Indian Ocean that is an overseas departments and regions of France, overseas department and region of France. Part of the Mascarene Islands, it is located approximately east of the island of Madagascar and southwest of the island of Mauritius. , it had a population of 896,175. Its capital and largest city is Saint-Denis, La Réunion, Saint-Denis. Réunion was uninhabited until French immigrants and colonial subjects settled the island in the 17th century. Its tropical climate led to the development of a plantation economy focused primarily on sugar; slaves from East Africa were imported as fieldworkers, followed by Malays, Annamite, Vietnamese, Chinese, and Indians as indentured laborers. Today, the greatest proportion of the population is of mixed descent, while the predominant language is Réunion Creole, though French remains the sole official language. Since 1946, Réunion has been governed as a regions of France, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Madagascar
The Colony of Madagascar and Dependencies () was a French colony off the coast of Southeast Africa between 1897 and 1958 in what is now Madagascar. The colony was formerly a protectorate of France known as Malagasy Protectorate. The protectorate became a colony, following Queen Ranavalona III's exile to Réunion. In 1958, the colonial administration in Madagascar was abolished, and it became an autonomous territory of the French Community as the Malagasy Republic, which existed until 1975. History Background and French protectorate The United Kingdom had been an ally of Madagascar. In May 1862, John Russell, 1st Earl Russell, Britain's foreign secretary, instructed Connolly Pakenham that Radama II should keep the country away from foreign powers. In 1882, the French started to occupy much of Madagascar's northern and western territories. In 1883, the Franco-Hova Wars commenced between France and Merina Kingdom, but the outcome remained inconclusive. The British gov ...

Solar Eclipse Of May 18, 1901
A total solar eclipse occurred at the Moon's descending node of orbit on Saturday, May 18, 1901, with a magnitude of 1.068. 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. Occurring about 23 hours after perigee (on May 17, 1901, at 6:50 UTC), the Moon's apparent diameter was larger. The path of totality crossed French Madagascar (the part now belonging to Madagascar), Réunion, British Mauritius (now Mauritius), Dutch East Indies (now Indonesia), and British New Guinea (now belonging to Papua New Guinea). A partial eclipse was visible for parts of East Africa, South Asia, Southeast Asia, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terrestrial Time
Terrestrial Time (TT) is a modern astronomical time standard defined by the International Astronomical Union, primarily for time-measurements of astronomical observations made from the surface of Earth. For example, the Astronomical Almanac uses TT for its tables of positions ( ephemerides) of the Sun, Moon and planets as seen from Earth. In this role, TT continues Terrestrial Dynamical Time (TDT or TD),TT is equivalent to TDT, see IAU conference 1991, Resolution A4, recommendation IV, note 4. which succeeded ephemeris time (ET). TT shares the original purpose for which ET was designed, to be free of the irregularities in the rotation of Earth. The unit of TT is the SI second, the definition of which is based currently on the caesium atomic clock,IAU conference 1991, Resolution A4, recommendation IV, part 2 states that the unit for TT is to agree with the SI second 'on the geoid'. but TT is not itself defined by atomic clocks. It is a theoretical ideal, and real clocks can onl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Eclipse Of July 11, 1991
A total solar eclipse occurred at the Moon's descending node of orbit on Thursday, July 11, 1991, with a magnitude of 1.08. 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. Occurring about 8 hours after perigee (on July 11, 1991, at 11:00 UTC), the Moon's apparent diameter was larger. The eclipse lasted for 6 minutes and 53.08 seconds at the point of maximum eclipse. There will not be a longer total eclipse until June 13, 2132. This was the largest total solar eclipse of Solar Saros series 136. This eclipse was the most central total eclipse in 800 years, with a gamma of −0.00412. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concorde
Concorde () is a retired Anglo-French supersonic airliner jointly developed and manufactured by Sud Aviation and the British Aircraft Corporation (BAC). Studies started in 1954, and France and the United Kingdom signed a treaty establishing the development project on 29 November 1962, as the programme cost was estimated at £70 million (£ in ). Construction of the six prototypes began in February 1965, and the first flight took off from Toulouse on 2 March 1969. The Market (economics), market was predicted for 350 aircraft, and the manufacturers received up to 100 option orders from many major airlines. On 9 October 1975, it received its French certificate of airworthiness, and from the Civil Aviation Authority (United Kingdom), UK CAA on 5 December. Concorde is a tailless aircraft design with a narrow fuselage permitting four-abreast seating for 92 to 128 passengers, an ogival delta wing, and a Droop nose (aeronautics), droop nose for landing visibility.

Eddington Experiment
The Eddington experiment was an observational test of general relativity, organised by the British astronomers Frank Watson Dyson and Arthur Stanley Eddington in 1919. The observations were of the total solar eclipse of 29 May 1919 and were carried out by two expeditions, one to the West African island of Príncipe, and the other to the Brazilian town of Sobral. The aim of the expeditions was to measure the gravitational deflection of starlight passing near the Sun. The value of this deflection had been predicted by Albert Einstein in a 1911 paper; however, this initial prediction turned out not to be correct because it was based on an incomplete theory of general relativity. Einstein later improved his prediction after finalizing his theory in 1915 and obtaining the solution to his equations by Karl Schwarzschild. Following the return of the expeditions, the results were presented by Eddington to the Royal Society of London and, after some deliberation, were accepted. Widespr ...
