Question: What was the name of the radio telescope the surpassed the Dwingeloo Radio Observatory?
Context: The Algonquin 46m radio telescope (ARO) is a radio telescope at the Algonquin Radio Observatory, Canada.  This radio telescope is historically famous for taking part in the first successful very long baseline interferometry experiment in the 1960s, where it was experimentally arrayed with the 26-metre Telescope at the Dominion Radio Astrophysical Observatory near Penticton, British Columbia. The Suffa RT-70 radio telescope is an RT-70 radio telescope under construction at the Suffa Radio Observatory on the Suffa plateau, Uzbekistan.  Construction began in the late 80's, but was put on hold when the USSR fell.  s of 2008 , construction had resumed, with an updated emphasis on millimeter-wave band observations at 100–300 GHz.  s of 2014 , construction was reported to be 50% complete. The Effelsberg 100-m Radio Telescope is a radio telescope in the Ahrgebirge (part of the Eifel) in Bad Münstereifel, Germany.  For 29 years the Effelsberg Radio Telescope was the largest fully steerable radio telescope on Earth.  In 2000 it was surpassed by the Robert C. Byrd Green Bank Telescope in Green Bank, US which has a slightly larger elliptical 100 by 110-metre aperture. Reber Radio Telescope is a parabolic radio telescope built by astronomer Grote Reber in his back yard in Illinois in 1937, implementing an earlier proposal of Karl Jansky, the discoverer (1931) of radio waves emanating from the Milky Way.  It was the second radio telescope ever built (after Jansky's dipole array), and the first parabolic radio telescope, serving as a prototype for the first large dish radio telescopes such as the Green Bank Telescope and Lovell Telescope constructed after World War 2.  Made of sheet metal with a 31.4 foot (9 meter) aperture and 20 foot (6 meter) focal length, it was the largest parabolic dish in existence at the time.  Reber was the world's only radio astronomer at the time, and his construction of the telescope and the sky surveys he did with it helped found the field of radio astronomy, revealing radio sources such as Cassiopeia A and Cygnus X-1 for the first time. The Dwingeloo Radio Observatory is a single-dish radio telescope near the village of Dwingeloo (] ) in the northeastern Netherlands.  Construction started in 1954, and the telescope was completed in 1956.  The radio telescope has a diameter of 25 m.  At the time of completion it was the largest radio telescope in the world, but it was overtaken in 1957 by the 76-m Lovell Telescope. The Ohio Sky Survey was an astronomical survey of extragalactic radio sources. Data were taken between 1965 and 1971 using the Big Ear radio telescope at the Ohio State University Radio Observatory (OSURO), also known as the "Big Ear Radio Observatory (BERO)". Giant Ukrainian Radio Telescope (GURT, Ukrainian: "Гігантський Український Радіотелескоп", "ГУРТ") is a low frequency (8-80 MНz) radio telescope which is being developed, built and operated by Institute of Radio Astronomy of National Academy of Sciences of Ukraine (IRA NASU).  It is located at S. Y. Braude radio astronomical observatory in Kharkiv oblast of Ukraine.  The GURT system is designed to be an extension of Ukrainian T-shaped Radio telescope, second modification (UTR-2) in terms of spatial dimensions and frequency range.  The goals of creating this new instrument include enhancement of UTR-2 functional properties and contribution to the progress of low frequency radio astronomy in synergy with other distant instruments. The Lovell Telescope is a radio telescope at Jodrell Bank Observatory, near Goostrey, Cheshire in the north-west of England.  When construction was finished in 1957, the telescope was the largest steerable dish radio telescope in the world at 76.2 m (250 ft) in diameter; The Allen Telescope Array (ATA), formerly known as the One Hectare Telescope (1hT), is a radio telescope array dedicated to astronomical observations and a simultaneous search for extraterrestrial intelligence (SETI).  The array is situated at the Hat Creek Radio Observatory, 290 mi northeast of San Francisco, California. The Submillimeter Telescope (SMT), formerly known as the Heinrich Hertz Submillimeter Telescope, is a submillimeter wavelength radio telescope located on Mount Graham, Arizona.  It is a 10-meter-wide parabolic dish inside a building to protect it from bad weather.  The building front doors and roof are opened when the telescope is in use.  The telescope's construction was finished in 1993.  Along with the 12 Meter Telescope on Kitt Peak, this telescope is maintained by the Arizona Radio Observatory, a division of Steward Observatory at the University of Arizona.
