The complex of optical instruments of the ISTP SB RAS was commissioned in Tory

IrkutskRepublic of Buryatia, 16.08.22 (IA “Teleinform”), – Complex of optical instruments of the Institute of Solar-Terrestrial Physics of the Siberian branch of the Russian Academy of Sciences, located in the village of Torah (Republic of Buryatia), in operation. The Ministry of Natural Resources and Ecology of the Russian Federation issued the official permit to put the facility into operation. According to the decree of the Government of the Russian Federation, ISTP SB RAS was supposed to start the facility before the end of 2022. The construction of the complex was carried out under the conditions of the operational observatory, the institute continued to fulfill the state task during all these years.

Complex of optical instruments is located on the territory of the Tunkinsky National Park, therefore the object passed a number of surveys, including environmental ones, before obtaining permission.

The facility was built as part of the project National Heliogeophysical Complex RAS on the territory of the institute’s geophysical observatory, it was built over three years. The complex is designed to study various processes and phenomena in the upper layers of the Earth’s atmosphere, reflecting their change under the influence of large-scale meteorological disturbances, geomagnetic storms, spacecraft. This knowledge is important for the successful development of the modern space industry: radio communication, geolocation, observation of the Earth’s surface. In addition, studies of the upper atmosphere will make it possible to reasonably predict dangerous situations for spacecraft that may arise as a result of the influence of the solar wind and wave processes on the lower atmosphere, to determine the degree of influence of anthropogenic factors and the measure of their negative impact. All this information will help develop recommendations for the safe operation of near-Earth spaces.

Complex of optical instruments of ISTP SB RAS in Tory was commissioned

All modern equipment purchased for the complex of optical instruments has been successfully assembled and tested. These are diffraction spectrometers for the visible and infrared optical range for detailed mapping of the spectral pattern of the natural glow in the Earth’s night atmosphere, Fabry-Perot interferometers adapted for aeronomic research, ultra-wide-angle optical systems and fast photometers that record properties of the temporal and spatial structure of variations in the natural glow of the night sky. ISTP SB RAS also designed and manufactured special lifting mechanisms, which at dusk lift the measuring equipment under the transparent dome of the technical building.

Currently, experimental observations of the night sky are being carried out in Torah. The old and new equipment in the complex work simultaneously to maintain the duration of the observation series and get a conversion factor, then the old instruments will be removed from the observations. The purpose of the observations is to analyze the data obtained at the moments when geomagnetic storms, earthquakes and other significant geophysical events occurred, both global and occurred in the Baikal region, as well as to determine the features of daily seasonal variations in parameters of the upper atmosphere. In addition, the institute can perform observations at the request of other organizations and departments, conducting observation campaigns timed to coincide with such events, for example, as spacecraft or their maneuvering over a geophysical observatory.

Academic supervisor for ISTP SB RAS Academician Helium Zherebtsov emphasized that the complex of optical instruments became the launch object of the project of the National Heliogeophysical Complex of the Russian Academy of Sciences:

— The construction of the complex is divided into two stages. The first of them included the design of KST – a large solar telescope with a mirror diameter of 3 meters in Mondy (last year we completed it and received a positive conclusion from Glavgosexpertiza), the design and construction of a complex of optical instruments in Tory. The final purpose of the first stage of the oil and gas complex of the Russian Academy of Sciences is the design and construction of a radio heliograph in the Badary channel, with its commissioning, the first stage will be completed. Antenna systems, four dormitories for observers and a technical building have now been built there. The radio heliograph is built on the basis of one of the largest radio interferometers in Russia, the Siberian Solar Radio Telescope with 256 antennas; observations at the radio telescope were not interrupted during the construction of the radio heliograph.

Helium Zherebtsov reminded that the NGK RAS is designed to study the processes occurring in the Earth’s atmosphere, including near-Earth space, to study the effect of the solar wind on the magnetosphere and ionosphere and the Earth’s atmosphere.

– The creation of the complex will provide an opportunity to ensure the fundamental advantage of domestic science in the field of solar-terrestrial physics for the next 25-30 years. This tool system will make it possible to gain new knowledge about the processes that take place on the Sun and in outer space near the Earth. It is important that this is not only basic knowledge, but also applied knowledge that helps us minimize the possible consequences of powerful solar flares for the entire technosphere, both on Earth and in space.

  • Reference: The National Heliogeophysical Complex of the Russian Academy of Sciences will include a multi-wavelength radioheliograph (Badary channel, Buryatia), a solar coronagraph telescope with a main mirror diameter of three meters (near the village of Mondy, Buryatia), a complex of optical instruments (near the village of Tory, Buryatia ), a radar system, mesostratospheric lidar – a powerful laser for studying the upper layers of the atmosphere (both instruments will be built on the coast of Lake Baikal in the Irkutsk region), a heating plant (near Angarsk) and a control center (in Irkutsk).
