Astronomy:Itapetinga Radio Observatory
Pierre Kauffman Radio Observatory (Portuguese: Rádio Observatório Pierre Kauffman - ROPK), also known as the Itapeting Radio Observatory (Portuguese: Rádio Observatório de Itapetinga - ROI), is a radio observatory located in the municipality of Atibaia in the state of São Paulo in Brazil . It is located approximately 7.5 km (4.7 mi) south of Atibaia and 40 km (25 mi) north of São Paulo. ROI was founded in 1970 by Universidade Presbiteriana Mackenzie (UPM).[1] Control of the facility was passed to the National Institute for Space Research (INPE) in 1982.[1] Today it is managed jointly by INPE, UPM, University do Vale do Paraíba (Univap), Universidade de São Paulo (USP), and Universidade Federal de Itajubá (UNIFEI).[2] In addition to the telescopes, the observatory has living quarters for visiting scientists. ROI is located inside a small radio quiet zone.[3] It was renamed in 2016 after Pierre Kauffman.
Telescopes
- A 13.7 m (45 ft) dish antenna was completed in 1974. It is housed in a radome which was replaced in 1990. It observes in bands from 18 GHz to 26 GHz and 40 GHz to 50 GHz simultaneously.[4] It is used for both astronomical and solar observations.[5][6]
- The Solar Patrol Equipment (Portuguese: Equipamento de Patrulhamento Solar - SPUA) is an array of 1.5 m (4.9 ft) dish antennas on a common mount. It monitors intensity and linear polarization of radio waves from the Sun at 12 GHz.[4]
- The Solar Radio Polarimeter (Portuguese: Rádio Polarímetro Solar - RaPoSo) is a 1.5 m (4.9 ft) antenna with two low-noise receivers centered at 7 GHz. It monitors the intensity and circular polarization of radio waves from the Sun.[7] It was originally located at UPM's defunct Umuarama Radio Observatory near Campos do Jordão and is the oldest telescope at ROI.[8][9]
