Scientific goals of optical instruments of the National Heliogeophysical Complex
Solar-Terrestrial Physics, 2020 Studies of the upper atmosphere have to be performed using optical photometric and spectrometric means. Modern devices allow precise photometry of the glow of the night atmosphere — airglow — with high temporal spatial and spectral resolution.

Machine learning in solar physics
Living Reviews in Solar Physics, 2023 AbstractThe application of machine learning in solar physics has the potential to greatly enhance our understanding of the complex processes that take place in the atmosphere of the Sun. By using techniques such as deep learning, we are now in the position to analyze large amounts of data from solar observations and identify patterns and trends that ...

Living Reviews in Solar Physics, 2014 The infrared solar spectrum contains a wealth of physical data about our Sun, and is explored using modern detectors and technology with new ground-based solar telescopes. The scientific motivation behind exploring these wavelengths is presented, along with a brief look at the rich history of observations here. Several avenues of solar physics research

Project of the Large Solar Telescope with mirror 3 m in diameter
Solar-Terrestrial Physics, 2020 One of the most important problems of modern solar physics is the observation of the small-scale structure of the solar atmosphere at various heights (including the chromosphere and corona) in different spectral lines.

Solar physics at the Einstein Tower [PDF]
Astronomische Nachrichten, 2016 AbstractThe solar observatory Einstein Tower (Einsteinturm) at the Telegrafenberg in Potsdam is both a landmark of modern architecture and an important place for solar physics. Originally built for high‐resolution spectroscopy and measuring the gravitational redshift, research shifted over the years to understanding the active Sun and its magnetic ...

CALIBRATION OF SIBERIAN RADIOHELIOGRAPH IMAGES
Solar-Terrestrial Physics, 2019 We discuss the method for automatic calibration of solar radio images derived from the first stage of the multiwave Siberian Radioheliograph (SRH-48). SRH is a 48-element T-shaped radiointerferometer in the 4–8 GHz frequency range. Since the end of 2017,
