Kodaikanal Solar Observatory
The Kodaikanal Solar Observatory is a solar observatory owned and operated by the Indian Institute of Astrophysics. It is on the southern tip of the Palani Hills from Kodaikanal town. The Evershed effect was first detected at this observatory in January 1909. Solar data collected by the lab is the oldest continuous series of its kind in India. Precise observations of the equatorial electrojet are made here due to the unique geography of Kodaikanal. Ionospheric soundings, geomagnetic, F region vertical drift and surface observations are made here regularly. Summaries of the data obtained are sent to national ( India Meteorological Department) and global (World Meteorological Organization, Global Atmosphere Watch) data centers. They have a full-time staff of two scientists and three technicians. History As early as 1881, Mr. Blanford, then Meteorological Reporter to the Government of India, recommended "the improvement of the work of solar observations in order to obtain a ...

Norman Robert Pogson
Norman Robert Pogson, CIE (23 March 1829 – 23 June 1891) was an English astronomer who worked in India at the Madras observatory. He discovered several minor planets and made observations on comets. He introduced a mathematical scale of stellar magnitudes with the ratio of two successive magnitudes being the fifth root of one hundred (~2.512) and referred to as Pogson's ratio. Youth and education Norman was born in Nottingham, the son of George Owen Pogson, a hosiery manufacturer, lace dealer and commission agent, "with enough income to support an extended family", and his wife, Mary Ann. It was intended that he should follow his father into business, and he was accordingly sent for "commercial education", but he was fascinated by science, and his mother supported and encouraged this interest. His early education was largely informal. He left school at 16, intending to teach mathematics. At the age of eighteen, he calculated with the help of John Russell Hind of the Royal ...

John Evershed
John Evershed CIE FRS FRAS (26 February 1864 – 17 November 1956) was an English astronomer. He was the first to observe radial motions in sunspots, a phenomenon now known as the Evershed effect. Biography Evershed was born in Gomshall, Surrey to John and Sophia (née Price) Evershed. He made the discovery which bears his name while at Kodaikanal Observatory in 1909. After retirement in 1923 he set up a private observatory at Ewhurst, Surrey and built a large spectroheliograph of special design and another with high-dispersion liquid prism. He continued to study the wave-lengths of H and K lines in prominences, giving values of the solar rotation at high levels in different latitudes and at different phases of the solar cycle. Work continued until 1950 when the observatory closed and he presented some of his instruments to the Royal Greenwich Observatory at Herstmonceux. In the autumn of 1890 was a founding member of the British Astronomical Association. He directed i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madras Observatory
The Madras Observatory was an astronomical observatory which had its origins in a private observatory set up by William Petrie in 1786 and later moved and managed by the British East India Company from 1792 in Madras (now known as Chennai). The main purpose for establishing it was to assist in navigation and mapping by recording the latitude and maintaining time standards. In later years the observatory also made observations on stars and geomagnetism. The observatory ran from around 1792 to 1931 and a major work was the production of a comprehensive catalogue of stars. History The observatory was established due to the efforts of William Petrie, an amateur astronomer who had a small private observatory at Egmore in Madras. Petrie's original observatory was established in 1786 and was made of iron and timber. In 1789, Petrie gifted his instruments to the Madras Government before retiring to England. Sir Charles Oakley accepted Petrie's plea to establish an official observatory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
