Siberian solar radio telescope — SSRT — one of the largest astronomical instruments. It is located in a picturesque wooded valley separating the two mountain ranges of the Eastern Sayan mountains, 220 km from Irkutsk.

Summary

[edit]
Description
Русский: Обсерватория "Бадары" расположена в покрытой лесом долине, разделяющей два горных хребта Восточных Саян, на расстоянии 220 км от Иркутска. Представляет собой крестообразный интерферометр, состоящий из двух линий 128 x 128 параболических антенн диаметром 2,5 метра, установленных эквидистантно с шагом 4,9 метра и ориентированных в направлениях восток-запад и север-юг. Строительство телескопа началось в 1974 году. Окончательный ввод в эксплуатацию был осуществлен в августе 1984 года. Находится в Тункинской долине между хребтами Восточных Саян иХамар-Дабан в 220 км от Иркутска. Радиотелескоп представляет собой крестообразный радиоинтерферометр, состоящий из двух линий параболических антенн по 128 в каждой луче, ориентированных в направлениях восток-запад и север-юг. Антенны имеют диаметр 2,5 м и установлены на равном расстоянии в 4,9 м друг от друга. На момент создания ССРТ, он не имел мировых аналогов, так как считалось, что получение изображения Солнца с 256 антенн — трудноразрешимая задача. Авторский коллектив создателей телескопа был удостоен премии Правительства РФ в области науки и техники за 1996 год. Радиотелескоп предназначен для изучения солнечной атмосферы в микроволновом диапазоне (5,7 ГГц) в интенсивности и круговой поляризации. Проводящиеся наблюдения дают важную информацию как о солнечных активных областях, происходящих в них вспышечных явлениях, выбросах корональной массы, так и сведения о «спокойных» объектах на Солнце, таких как корональные дыры, яркие корональные точки, волокна.
English: Badary Observatory is located in a wooded valley separating two mountain ranges of the Eastern Sayan mountains, at a distance of 220 km from Irkutsk. It is a cross-shaped interferometer consisting of two lines of 128 x 128 parabolic antennas with a diameter of 2.5 meters, installed equidistant at a step of 4.9 meters and oriented in the East-West and North-South directions. Construction of the telescope began in 1974. The final commissioning was carried out in August 1984. Located in the Tunka valley between the ridges of the Eastern Sayan mountains, Hamar-Daban, 220 km from Irkutsk. The radio telescope is a cross-shaped radio interferometer consisting of two lines of 128 parabolic antennas in each beam, oriented in the East-West and North-South directions. The antennas have a diameter of 2.5 m and are installed at an equal distance of 4.9 m from each other. At the time of creation of SSRT, it had no world analogs as it was considered that obtaining the image of the Sun from 256 antennas — a difficult task. The team of authors of the telescope was awarded the Russian Government prize in science and technology for 1996. The radio telescope is designed to study the solar atmosphere in the microwave range (5.7 GHz) in intensity and circular polarization. The observations provide important information about both the solar active areas, their flare phenomena, coronal mass emissions, and information about "quiet" objects in the Sun, such as coronal holes, bright coronal points, fibers.
