OBSERVATIONS OF SPACE DEBRIS IN THE VICINITY OF ORBITS OF GLOBAL NAVIGATION SATELLITE SYSTEMS

Solar-Terrestrial Physics, 2020
The problem of the amount and characteristics of space debris in the vicinity of orbits of Global Navigation Satellite Systems (GNSS) is of significant interest from the viewpoint of safe operation of these systems.

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 ...

Solar Neutrinos: Where We Are, What We Need [PDF]

, 1998
This talk compares standard model predictions with the results of solar neutrino experiments. Here `standard model' means the combined standard model of minimal electroweak theory plus a standard solar model. I emphasize the importance of recent analyses

Registering upper atmosphere parameters in East Siberia with Fabry–Perot Interferometer KEO Scientific “Arinae”

Solar-Terrestrial Physics, 2017
We describe the Fabry—Perot interfero-meter designed to study Earth’s upper atmosphere. We propose a modification of the existing data processing method for determining the Doppler shift and Doppler widening and also for separating the observed line ...

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 ...

Spectral and photometric characteristics of mid-latitude auroras during the magnetic storm of March 17, 2015

Solar-Terrestrial Physics, 2018
We study the spatiotemporal dynamics of mid-latitude aurora from observations in the south of Eastern Siberia during St. Patrick’s severe geomagnetic storm on March 17, 2015. We perform a morphological analysis of characteristics of the observed auroras.

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 ...

Solar Neutrinos [PDF]

, 2012
The study of solar neutrinos has given since ever a fundamental contribution both to astroparticle and to elementary particle physics, offering an ideal test of solar models and offering at the same time relevant indications on the fundamental ...
