Multi-wave radioheliograph

2023: Commissioning in Buryatia

On November 28, 2023, the Institute of Solar-Terrestrial Physics of the Siberian Branch of the Russian Academy of Sciences (SB RAS) announced the commissioning of a multi-wave radioheliograph. This is the world's first complex of this type, which is designed to study the sun.

The system is located on the territory of the Badary radio astronomy observatory in the Tunkinsky district of Buryatia. The multi-wave radio heliograph consists of three radio telescopes and has a total of 528 antennas. The frequency range is from 3 to 24 GHz. Antennas of each radio telescope are arranged in the form of letter "T" with mainly equal pitch between adjacent modules. This configuration is claimed to allow calibration of the entire radio telescope along with imaging.

A multi-wave radioheliograph was put into operation

The complex makes it possible to explore different layers of the sun's corona, each of which emits at its own frequency. This allows three-dimensional coronal activity data to be obtained. The tool allows scientists to observe and predict processes in the global Sun - system, Earth build 3D models of near-solar outer space, and conduct fundamental research. In addition, experts will be able to predict negative phenomena caused by solar activity and their consequences for the Earth's technosphere.

In general, a radiogeliographer will help in the study and understanding of the mechanisms of solar activity. The tool allows you to take pictures of the sun in a range that was not previously used for these purposes. The multi-wave radiogeliograph is one of the objects of the National Heliogeophysical Complex of the Russian Academy of Sciences. This initiative also includes the design of a large solar coronograph telescope with a mirror with a diameter of 3 meters and the creation of a system of optical instruments in Tori (Buryatia), which was commissioned in 2022.^[1]
