Новая система радаров – субпроект, который реализует Институт солнечно-земной физики Сибирского отделения Российской академии наук (ИСЗФ СО РАН) в рамках реализации мегапроекта «Национальный гелиогеофизический комплекс РАН» (НГК РАН). Главгосэкспертиза России выдала положительное заключение на первый этап строительства.

Оно будет развернуто в местности Харикта в Ольхонском районе, Иркутской области на территории новой Байкальской обсерватории физики атмосферы и экологического мониторинга ИСЗФ СО РАН.

На первом этапе будут возведены антенные комплексы «Север» и «Юг», а также создана необходимая инфраструктура для их эффективной работы, что позволит оперативно контролировать состояние как высокоширотной, так и среднеширотной ионосферы

«Новое поколение отечественных радаров разрабатывает Институт солнечно-земной физики. Они отличаются более высокой чувствительностью к различным факторам влияния солнечного ветра и других космических процессов на земную ионосферу. В том числе таким, как геомагнитные возмущения, влияющие на работу связи, навигации и других технологических систем. Новый инструмент позволит расширить возможности мониторинга явлений ближнего и дальнего космоса», — рассказал главный эксперт проекта Дмитрий Придатченко.

Помимо системы радаров будут построены радиотехнического и астрофизического оборудования на площадке системы радаров построят пункты высокоточной геодезической сети, здание управления, а также инженерно-технические коммуникации. Все проектные решения разработаны с учетом повышенной сейсмичности участка строительства.

Застройщик — Федеральное государственное бюджетное учреждение науки «Институт солнечно-земной физики Сибирского отделения Российской академии наук» (ИСЗФ СО РАН).

The Institute of Solar-Terrestrial Physics SB RAS hosted the XV scientific school conference "Man and Space". The event brought together young researchers from Irkutsk Oblast and the Republic of Buryatia, whose projects successfully passed the qualifying round.

The Institute of Solar-Terrestrial Physics SB RAS and Dorzhi Banzarov Buryat State University have signed an agreement to establish a new Space Physics Laboratory. According to Tatiana Syrenova, head of the Laboratory, Candidate of Physical and Mathematical Sciences, and Researcher at the ISTP SB RAS Laboratory of Atmospheric Physics, Within the framework of the partnership, a new Master’s specialization in Space Physics has been introduced at BSU. The first student intake is planned for September this year.

Modern space science is built not only on telescopes and satellites but also on the passion of people exploring the Universe’s mysteries. How does the Sun affect our planet? Why has Irkutsk become a global hub for near-Earth space research? And what large-scale scientific facilities are being created by the Institute’s researchers today?

Students and schoolchildren are invited to find out the answers to these and many other questions at the Open House on April 19. The event is organized by the Scientific Youth Council of ISTP SB RAS.

A series of joint experiments aimed at measuring the temperature of Earth’s upper atmosphere has commenced at the Irkutsk Incoherent Scatter Radar (Usolye-7) and the Complex of Optical Instruments (Tory settlement, Buryat Republic), both operated by the Institute of Solar-Terrestrial Physics SB RAS. The researchers intend to conduct these measurements across various seasons throughout an entire 11-year solar cycle to accumulate the essential dataset.

Director of ISTP SB RAS Andrey Medvedev and First Deputy Director Sergey Olemskoy informed journalists about the Institute's performance in 2025 and plans for the near future.

Scientists at the Institute of Solar-Terrestrial Physics SB RAS offered a method that enhances the precision of ultraviolet emission measurements at satellites operated by NASA and ESA. Their paper titled “Calibration of the degrading absolute SOHO/SEM ultraviolet flux using ground-based solar activity indices” was published on January 1, 2026, in Advances in Space Research, an official journal of the Committee on Space Research under the International Council for Scientific Unions. The study is authored by Yuri Yasyukevich, Deputy Director of ISTP SB RAS and Doctor of Physical-Mathematical Sciences, Ekaterina Danilchuk and Larisa Kashapova, both Candidates of Physical and Mathematical Sciences, and researcher Artem Vesnin.

A project led by Irina Medvedeva, Candidate of Phys.-Mat. Sciences, a leading researcher at the Institute of Solar-Terrestrial Physics, SB RAS, titled “Effects of Winter Sudden Stratospheric Warmings in the Upper Neutral Atmosphere and Ionosphere at Middle and High Latitudes: Diagnostics and Analysis” has been awarded a grant from the Russian Science Foundation. The two-year project will receive funding amounting to 1.5 million rubles for the year 2026. Approximately five thousand applications were submitted to the RSF competition “Fundamental and exploratory research by small research groups” As a result of expert evaluation, 1154 projects have been supported.  

A team of scientists from the V.E. Zuev Institute of Atmospheric Optics SB RAS (Tomsk) and the Institute of Solar-Terrestrial Physics SB RAS (Irkutsk) predicts a nervous, contrasting winter in Siberia with alternating frosts and thaws. According to the researchers, such weather pattern stems from unstable atmospheric conditions, particularly within the stratosphere—a layer situated between 11 and 50 km above Earth's surface. Due to a sudden stratospheric warming event in November, the polar vortex – a giant ring of cold air rotating over the Arctic – has become destabilized.
