Statistical relation of traveling ionospheric disturbances with neutral wind and disturbances in the stratosphere

Solar-Terrestrial Physics, 2022
Using the representative statistics on traveling ionospheric disturbances (TIDs) obtained by Yekaterinburg and Magadan radars, we have shown that distributions of TIDs and average TID velocities by azimuths and local time agree well with the hypothesis ...

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 ...

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,

Solar neutrino physics with Borexino [PDF]

SciPost Physics Proceedings, 2019
We present the most recent solar neutrino results from the Borexino experiment at the Gran Sasso underground laboratory. In particular, refined measurements of all neutrinos produced in the pp fusion chain have been made. It is the first time that the same detector measures the entire range of solar neutrinos at once. These new data weakly favor a high-

Estimation of the contributions of conductance and electric field to the intensity of field-aligned currents in the night polar ionosphere during substorm expansion phase

Геодинамика и тектонофизика, 2019
Based on the output data of the magnetogram inversion technique, we analyze the dynamics of the Pedersen ionospheric currents and field-aligned currents (FACs) in the night mesoscale cells of the three main large-scale Iijima and Potemra Regions (R1, R2 ...

All-atmosphere IS-MST Radar

Solar-Terrestrial Physics, 2020
The IS-MST radar, as the name implies, combines two different methods for studying the atmosphere using a backscatter signal. Turbulent fluctuations of the medium cause scattering in the mesosphere—stratosphere—troposphere (MST). In the upper atmosphere,

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 ...
