SOLAR ACTIVITY RESEARCH AT THE BAIKAL ASTROPHYSICAL OBSERVATORY OF ISTP SB RAS
Journal Title: Solar-Terrestrial Physics - Year 2019, Vol 5, Issue 3
Abstract
The article presents the main results of solar studies carried out at the Baikal Astrophysical Observatory (BAO) of the Institute of Solar-Terrestrial Physics SB RAS (ISTP SB RAS) for 40 years. It outlines the history of BAO and lists its telescopes. Much attention is given to the Large Solar Vacuum Telescope (LSVT) designed to observe solar formations with high spatial and spectral resolution. Technical parameters of this instrument are specified along with some results of the studies carried out with it. Information about the full-disk chromospheric telescope and scientific problems solved with it is represented together with the basic scientific results. The telescope is used to study solar activity complexes and solar flares. References to the basic publications that have used BAO results are presented.

CONDITIONS FOR ARRIVAL OF SOLAR ENERGETIC PROTONS IN EARTH AFTER STRONG SOLAR FLARES
We analyze the Sun-to-Earth transport of energetic protons accelerated in solar flares. We use a model which assumes that protons move earthward in the Parker electromagnetic field. In this model, protons are shown to be...
FEATURES OF ARTIFICIAL IONOSPHERE TURBULENCE INDUCED BY THE O- AND X-MODE HF HEATING NEAR THE F2-LAYER CRITICAL FREQUENCY
We present experimental results from the studies of large-scale inhomogeneities along the external magnetic field with increased electron density, electron temperature, and excitation of elongated plasma waves (Langmuir...
REAL-TIME MONITORING OF COSMIC RAY ANISOTROPY PARAMETERS AND SHORT-TERM FORECASTING OF GEOMAGNETIC DISTURBANCES
SHICRA SB RAS, using data from the NMDB database, has implemented continuous monitoring of the dynamics of cosmic ray (CR) distribution parameters and the automatic forecasting of geomagnetic disturbance. Monitoring is b...
A QUIET DAY EMPIRICAL MODEL OF ELECTRON DENSITY IN THE INDIAN EQUATORIAL F-REGION
In this paper, we present a quiet day empirical model of electron density (Ne) for the Indian equatorial zone at an altitude of 500 km. The model is applicable to all levels of solar activity and is based on the observat...
SHAPE OF SPECTRUM OF GALACTIC COSMIC RAY INTENSITY FLUCTUATIONS
The impact of solar wind plasma on fluxes of galactic cosmic rays (CR) penetrating from the outside into the heliosphere with energies above ~1 GeV leads to temporal variations in the CR intensity in a wide frequency ran...
