Perth Observatory
The Perth Observatory is the name of two astronomical observatory, observatories located in Western Australia (WA). In 1896, the original observatory was founded in West Perth, Western Australia, West Perth on Mount Eliza (Western Australia), Mount Eliza overlooking the city of Perth (obs. code IAU code#319, 319). Due to the city's expansion, the observatory moved to Bickley, Western Australia, Bickley in 1965. The new Perth Observatory is sometimes referred to as Bickley Observatory (obs. code IAU code#322, 322, IAU code#323, 323). History First Perth Observatory The original Perth Observatory was constructed in 1896 and was officially opened in 1900 by John Forrest, the first premier of Western Australia. The observatory was located at Mount Eliza, Western Australia, Mount Eliza overlooking the city of Perth, Western Australia, Perth. Its chief roles were keeping Standard Time for Western Australia and meteorological data collection. The observatory dome was demolished in ...

Observatory
An observatory is a location used for observing terrestrial, marine, or celestial events. Astronomy, climatology/meteorology, geophysical, oceanography and volcanology are examples of disciplines for which observatories have been constructed. Historically, observatories were as simple as containing an astronomical sextant (for measuring the distance between stars) or Stonehenge (which has some alignments on astronomical phenomena). Astronomical observatories Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based. Ground-based observatories Ground-based observatories, located on the surface of Earth, are used to make observations in the radio and visible light portions of the electromagnetic spectrum. Most optical telescopes are housed within a dome or similar structure, to protect the delicate instruments from the elements. Telescope domes have a slit or other opening in the roof that can be opened during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adelaide Observatory
The Heights Observatory is an Astronomical Observatory at The Heights School in Modbury Heights, Adelaide, South Australia. It is sometimes known as the Adelaide Observatory, but it is not to be confused with the observatory formerly established at the University of Adelaide. History The Observatory consists of two buildings. In 1988–89, the Emanuel Papaelia Observatory (opened Nov'89) was built containing a 1963 vintage 12" Dall-Kirkham Cassegrain reflecting telescope belonging to the Astronomical Society of South Australia (ASSA), and originally housed at Marryatville High School. In 1996, a second building with a roll off roof (the Ingham Family Rooms) was constructed. This contained a second hand 10" Meade LX-200 Schmidt-Cassegrain telescope. In August 2011, the 10" Meade in the Inghams building was replaced by a 14" Meade LX-200 GPS-ACF. This was purchased with a grant from the Education Minister (Jay Weatherill), topped up with fund raising money from the STAR Gro ...

Northern Territory Borders
Today the Northern Territory's land borders are defined to the west by the 129° east longitude (129° east) with Western Australia, to the south by the 26th parallel south latitude (26° south) with South Australia and to the east by 138° east longitude (138° east) with Queensland; however, this is not where all borders are actually marked on the ground. The Northern Territory boundaries are shared with the West Australian border, the South Australian border, and the Queensland border. History 1788-1832 In 1788, Governor Phillip claimed the continent of Australia as far west as the 135th meridian east longitude (135° east) in accordance with his commission. ( 26 January 1788 – Map) On 16 July 1825, the western boundary of New South Wales was relocated to the line of 129° east to take in the new settlement at Melville Island. ( 16 July 1825 – Map). From 1825 to 1829 129° east was the NSW border. Following the settlement of the Swan River Colony in 1829 ( 2 May ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Longitude
Longitude (, ) is a geographic coordinate that specifies the east–west position of a point on the surface of the Earth, or another celestial body. It is an angular measurement, usually expressed in degrees and denoted by the Greek letter lambda (λ). Meridians are semicircular lines running from pole to pole that connect points with the same longitude. The prime meridian defines 0° longitude; by convention the International Reference Meridian for the Earth passes near the Royal Observatory in Greenwich, England on the island of Great Britain. Positive longitudes are east of the prime meridian, and negative ones are west. Because of the Earth's rotation, there is a close connection between longitude and time measurement. Scientifically precise local time varies with longitude: a difference of 15° longitude corresponds to a one-hour difference in local time, due to the differing position in relation to the Sun. Comparing local time to an absolute measure of time allows ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
129th Meridian East
The meridian 129° east of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, Asia, Australia, the Indian Ocean, the Southern Ocean, and Antarctica to the South Pole. The 129th meridian east forms a great circle with the 51st meridian west. In Australia, the meridian nominally defines the eastern border of Western Australia, and the western borders of the Northern Territory and South Australia. However, the border of Western Australia actually meets the Northern Territory border and South Australian border at the 26th parallel south, at what is known as Surveyor Generals Corner. From Pole to Pole Starting at the North Pole and heading south to the South Pole, the 129th meridian east passes through: : See also *128th meridian east The meridian 128° east of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, Asia, Australia, the Indian Ocean, the Southern Ocean, and Antarctica to the South ...

Argyle Downs
Argyle Downs is a pastoral lease and cattle station located about south east of Kununurra in the Kimberley region near the border of Western Australia and Northern Territory. It is operated by the Consolidated Pastoral Company. Description The station occupies an area of and is a mix of black soil plains and red basalt country with the Ord River and Lake Argyle situated on the western boundary. Currently the property annually turns off 7,500 head of cattle for live export to the south East Asia market. Stock horses are also bred and raised on the property for use on other stations. History The traditional owners of the area are the Malngin peoples. The area was settled in 1882 by Patrick and his brother Michael Durack, who arrived in the area after trekking across the north of the continent from Thylungra Station, their property on Coopers Creek in Queensland, where they left from in 1879 along with 7250 breeding cattle and 200 horses. The 3000 mile journey of cattle to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Michael Durack
Michael Patrick Durack, (22 July 1865 – 3 September 1950) was a Pastoralism, pastoralist and Western Australian pioneer, known as "M.P." or to the family as "Miguel". He was the son of Patrick Durack and Mary Costello, both Irish-Australians. Life and career Durack was educated at St Patrick's College, Goulburn along with his brother, John Wallace. In 1881 he bought in Queensland and established the Archerfield pastoral run. In 1882–83, his family went on an expedition to the Kimberley (Western Australia), Kimberley region of Western Australia. On his 21st birthday, he made the first sale of Kimberley cattle to a Halls Creek, Western Australia, Halls Creek butcher for £1,200 in raw gold. In 1894, a new shipping trade was established by Francis Connor and Denis Doherty from Wyndham, Western Australia, Wyndham to Perth. The Durack family became one of the main suppliers in this market, and eventually merged with their shipping agents to form Connor, Doherty & Durack Ltd, ...

Deakin, Western Australia
Deakin is a remote locality and is the last railway siding in Western Australia on the Trans-Australian Railway, and the closest to the border of Western Australia and South Australia, which is the 129th meridian east. Deakin is important in the history of South Australia South Australia (commonly abbreviated as SA) is a state in the southern central part of Australia. It covers some of the most arid parts of the country. With a total land area of , it is the fourth-largest of Australia's states and territories ... and Western Australia in the part it has played in the determinations of fixing the Western Australian border with South Australia by marking the border on the ground. Historic sites close to Deakin are the Deakin Pillar (1921), from which the position was determined of the Deakin Obelisk (1926), being about 2.82 km to the east of the Deakin Pillar. Both sites were used to fix the border, and the Deakin Obelisk is the point on the earth which determines th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Australian Borders
Today South Australia's land borders are defined to the west by the 129° east longitude (129° east) with Western Australia, to the north by the 26th parallel south latitude (26° south) with the Northern Territory and Queensland and to the east by 141° east longitude (141° east) with Queensland, New South Wales and Victoria; however, this is not where all borders are actually marked on the ground. The South Australian boundaries are shared with the West Australian border, the Northern Territory border, the Queensland borders, the New South Wales border and the Victorian border—that is, all states and territories except for the Australian Capital Territory and Tasmania. History 1788–1832 In 1788, Governor Phillip claimed the continent of Australia only as far west as the 135th meridian east longitude (135° east) in accordance with his commission.

Western Australia Border
The land border of the state of Western Australia (WA) bisects mainland Australia, nominally along 129th meridian east longitude (129° East). That land border divides WA from the Northern Territory (NT) and South Australia (SA). However, for various reasons, the actual border (as surveyed and marked or otherwise indicated on the ground) deviates from 129° East, and is not a single straight line. The Western Australian town closest to the border is Kununurra, which is about west of the border with the NT. The settlement outside WA that is closest to the border is Border Village, SA, which adjoins the border; the centre of Border Village is about from the border, on the Eyre Highway. Border delineation In some cases, the physical signage and structures that mark the actual border deviate from the 129th meridian. The Northern Territory border with Western Australia and the South Australian border with Western Australia are displaced east–west by approximately , as a resul ...

South Australian Government Astronomer
South is one of the cardinal directions or compass points. The direction is the opposite of north and is perpendicular to both east and west. Etymology The word ''south'' comes from Old English ''sūþ'', from earlier Proto-Germanic ''*sunþaz'' ("south"), possibly related to the same Proto-Indo-European root that the word ''sun'' derived from. Some languages describe south in the same way, from the fact that it is the direction of the sun at noon (in the Northern Hemisphere), like Latin meridies 'noon, south' (from medius 'middle' + dies 'day', cf English meridional), while others describe south as the right-hand side of the rising sun, like Biblical Hebrew תֵּימָן teiman 'south' from יָמִין yamin 'right', Aramaic תַּימנַא taymna from יָמִין yamin 'right' and Syriac ܬܰܝܡܢܳܐ taymna from ܝܰܡܝܺܢܳܐ yamina (hence the name of Yemen, the land to the south/right of the Levant).

Harold Curlewis
Harold Burnham Curlewis (6 October 1875 – 8 June 1968) was an Australian astronomer. He was Acting Government Astronomer and Meteorologist in Western Australia from 1912 until his appointment as Government Astronomer in 1920. He held that position until 1940 and is credited with keeping the Perth Observatory open in face of government opposition. The asteroid 3898 Curlewis is named in his honour. Birth and education Curlewis was born in Geelong, Victoria to Edgar and Louisa Curlewis and attended Newington College (1884–1893). In 1892 he won the Wigram Allen Scholarship, awarded by Sir George Wigram Allen, for mathematics, and in 1893 he won it for classics. At the end of 1893 Curlewis was named Dux of the College and received the Schofield Scholarship.''Newington College Register of Past Students 1863–1998'' (Sydney, 1999) Part 2 – The Lists He went up to the University of Sydney and in 1897 graduated as a Bachelor of Arts.
