GREAT See also:BRITAIN AND  See also:IRELAND A . Public Observatories . ' See also:Greenwich, royal obs., See also:lat . +51 ° 28' 38.4" . Founded in 1675 for the promotion of See also:astronomy and See also:navigation . The obs. have therefore from the first been principally intended to determine the positions of See also:standard stars, the See also:sun and See also:planets, and above all to follow the See also:motion of the See also:moon with as little interruption as possible, both on and outside the See also:meridian . Since 1873 spectroscopic obs. and a daily phot. See also:record of sun-spots have been taken . The eighth See also:satellite of See also:Jupiter was discovered photographically in 1908 . The obs. is under the direction of the astronomer-royal; and from the See also:time of its first astronomer, See also:Flamsteed, the institution has always maintained its See also:place in the foremost See also:rank of obs . Thus the obs. of See also:Bradley (ob . 1762) See also:form the See also:foundation of See also:modern stellar astronomy ; but it was especially during the directorship of See also:Airy (1835–1881) that the obs. See also:rose to its See also:present high See also:state of efficiency . There are now two See also:chief assistants, six assistants, and a See also:staff of computers employed .

The See also:

principal See also:instruments now in use are: a meridian circle by See also:Simms (and Ransomes and May as See also:engineers), erected in 1850, having a circle of 6-ft.

The 26-in. and the 9-in. were presented by See also:Sir H . See also:Thompson . The standard " motor See also:clock " is the centre of a See also:system of electrically-controlled clocks scattered over the See also:United See also:Kingdom . The magnetic and meteorological See also:department was founded in 1838; it contains a See also:complete set of instruments giving continuous phot. records . The Observations are published with all details from 1750, beginning with 1836 in See also:annual bulky See also:quarto volumes; See also:special results—e.g., See also:Star Catalogues, Reductions of Lunar and Planetary Observations—are published in See also:separate volumes .
