When the antenna was turned by 90 degrees at the maximum of the shower, the number of detections dropped to the background level, proving that the transient signals detected by radar were from meteors. On 9 and 10 October 1946, the telescope observed ionisation in the atmosphere caused by meteors in the Giacobinids meteor shower. It was used for astronomical observations in October 1946. It consisted of 7 elements of Yagi–Uda antennas. Jodrell Bank is primarily used for investigating radio waves from the planets and stars.Ī searchlight was loaned to Jodrell Bank in 1946 by the army a broadside array, was constructed on its mount by J. The first permanent building was near to the cabin and was named after it. Over the next few years, Lovell accumulated more ex-military radio hardware, including a portable cabin, known as a "Park Royal" in the military (see Park Royal Vehicles). The first time Lovell turned the radar on – 14 December 1945 – the Geminids meteor shower was at a maximum. The first staff were Alf Dean and Frank Foden who observed meteors with the naked eye while Lovell observed the electromagnetic signal using equipment. Lovell's main research was transient radio echoes, which he confirmed were from ionized meteor trails by October 1946. He moved the equipment to Jodrell Bank, 25 miles (40 km) south of the city, on 10 December 1945. He intended to use the equipment in Manchester, but electrical interference from the trams on Oxford Road prevented him from doing so. The equipment was a GL II radar system working at a wavelength of 4.2 m, provided by J. The site was first used for astrophysics in 1945, when Bernard Lovell used some equipment left over from World War II, including a gun laying radar, to investigate cosmic rays. The site was extended in 1952 by the purchase of a farm from George Massey on which the Lovell Telescope was built. It is named from a nearby rise in the ground, Jodrell Bank, which was named after William Jauderell, an archer whose descendants lived at the mansion that is now Terra Nova School. Jodrell Bank was first used for academic purposes in 1939 when the University of Manchester's Department of Botany purchased three fields from the Leighs.

The Crewe to Manchester Line passes by the site, and Goostrey station is a short distance away. The observatory is reached from the A535. The Jodrell Bank Visitor Centre and an arboretum are in Lower Withington, and the Lovell Telescope and the observatory near Goostrey and Holmes Chapel. Jodrell Bank Observatory is the base of the Multi-Element Radio Linked Interferometer Network (MERLIN), a National Facility run by the University of Manchester on behalf of the Science and Technology Facilities Council. There are three other active telescopes at the observatory the Mark II, and 42 ft (13 m) and 7 m diameter radio telescopes. Its diameter of 250 ft (76 m) makes it the third largest steerable radio telescope in the world. The main telescope at the observatory is the Lovell Telescope. It has since played an important role in the research of meteoroids, quasars, pulsars, masers and gravitational lenses, and was heavily involved with the tracking of space probes at the start of the Space Age. The observatory was established in 1945 by Bernard Lovell, a radio astronomer at the university, to investigate cosmic rays after his work on radar in the Second World War. Jodrell Bank Observatory ( / ˈ dʒ ɒ d r əl/ JOD-rəl) in Cheshire, England, hosts a number of radio telescopes as part of the Jodrell Bank Centre for Astrophysics at the University of Manchester.
