Birmingham Solar Oscillations Network
The Birmingham Solar Oscillations Network (BiSON) consists of a network of six remote solar observatories monitoring low-degree solar oscillation modes. It is operated by the High Resolution Optical Spectroscopy group of the School of Physics and Astronomy at the University of Birmingham, UK, in collaboration with Sheffield Hallam University, UK. They are funded by the Science and Technology Facilities Council ( STFC). The BiSON has been collecting data continuously on solar oscillations since 1976, making it the longest running helioseismology network with data covering three solar cycles.

Helioseismology
Helioseismology, a term coined by Douglas Gough, is the study of the structure and dynamics of the Sun through its oscillations. These are principally caused by sound waves that are continuously driven and damped by convection near the Sun's surface. It is similar to geoseismology, or asteroseismology (also coined by Gough), which are respectively the studies of the Earth or stars through their oscillations. While the Sun's oscillations were first detected in the early 1960s, it was only in the mid-1970s that it was realized that the oscillations propagated throughout the Sun and could allow scientists to study the Sun's deep interior. The modern field is separated into global helioseismology, which studies the Sun's resonant modes directly, and local helioseismology, which studies the propagation of the component waves near the Sun's surface. Helioseismology has contributed to a number of scientific breakthroughs. The most notable was to show the predicted neutrino flux from ...

OTC Satellite Earth Station Carnarvon
The OTC Satellite Earth Station Carnarvon, an Earth station in Australia, was established to meet the need for more reliable and higher quality communications for the Apollo program. NASA contracted Australia's Overseas Telecommunications Commission (OTC) "to provide an earth station near Carnarvon, Western Australia to link the NASA tracking station in that area to the control centre in the USA", also contracting COMSAT to launch three Intelsat-2 communications satellites. Television and NASA-assist operations The "sugar scoop" antenna became operational on 29 October 1966 when Intelsat-2A, the first of the three satellites launched, gave OTC and the Australian Broadcasting Commission a brief chance to test satellite television communications as the satellite drifted to ignominious failure over the Indian Ocean. On 24 November 1966, test patterns for the first live telecasts from Australia to England were successful. The next day, a live BBC television broadcast from a studi ...

Sutherland, Northern Cape
Sutherland is a town with about 2,841 inhabitants in the Northern Cape province of South Africa. It lies in the western Roggeveld Mountains in the Karoo. History Sutherland was founded in 1855 as a church and market town to serve the area's sheep farmers. By 1872 the town had a population of 138 registered citizens living in 19 houses. The large Dutch Reformed church in the centre of Sutherland was built in 1899. During the Anglo Boer War the church was used as a fort by garrisoned British soldiers. During the war a number of engagements between British and Boer forces occurred in the town. In one such engagement a force of 250 Boer commandos attacked the local British garrison for 10 hours. The ruins of a fort can be found on the outskirts of town on the hill called Rebelskop. This was named after this engagement. Economy Major economic activities include tourism and sheep farming. The area includes at least twelve registered B&B's, guest houses and guest farms. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South African Astronomical Observatory
South African Astronomical Observatory (SAAO) is the national centre for optical and infrared astronomy in South Africa. It was established in 1972. The observatory is run by the National Research Foundation of South Africa. The facility's function is to conduct research in astronomy and astrophysics. The primary telescopes are located in Sutherland, which is from Observatory, Cape Town, where the headquarters is located. The SAAO has links worldwide for scientific and technological collaboration. Instrumental contributions from the South African Astronomical Observatory include the development of a spherical aberration corrector and the Southern African Large Telescope (SALT). The Noon Gun on Cape Town's Signal Hill is fired remotely by a time signal from the Observatory.
