RESULTS OF JOINT OBSERVATIONS WITH SOLAR SPECTROPOLARIMETER OF METER RANGE WAVELENGTHS AND OTHER INSTRUMENTS
Journal Title: Solar-Terrestrial Physics - Year 2022, Vol 8, Issue 1
Abstract
Solar radiation is emitted in the wide frequency range from gamma to radio emission. Hence, joint observations from different instruments and frequency ranges let us to complete full representation of the evolution of solar events and confirm authenticity of data from specific instruments. In this article, we present comparative analysis data from Solar Spectropolarimeter of Meter Range wavelengths (SSMD) and other instruments. For the investigation we have chosen three solar events registered with SSMD in 2019: type III radio bursts on May 6 from 05:05 UT to 05:12 UT, type II radio bursts on May 6 from 05:12 UT to 05:19 UT, and type III radio bursts on April 14 from 05:03 UT to 05:21 UT. For comparison we apply data from the following instruments: SSMD, SRH (Siberian Radioheliograph), SDO/AIA (Atmospheric Imaging Assembly (AIA) on the Solar Dynamics Observatory (SDO)), Wind/WAVES (WAVES investigation on the WIND spacecraft), ground-based spectropolarimeter AMATERAS, spacecraft GOES-14. As a result, we can conclude that they are in good correlation with each other and correspond to outstanding characteristics for each event. The investigation also confirms the SSMD data authenticity.

Studying the small-scale structure of a polarization jet during the April 20, 2018 geomagnetic storm
In this work, we study the small-scale structure of a polarization jet in the subauroral region during the April 20, 2018 geomagnetic storm. We report measurement results of plasma parameters inside the polarization jet...
AMPLITUDE VARIATIONS OF THE REFLECTED SIGNAL DURING VERTICAL SOUNDING OF THE IONOSPHERE AT MIDDLE LATITUDES
In this paper, we discuss the main types of quasiperiodic variations in amplitudes of a reflected signal during vertical sounding of the ionosphere at middle latitudes. The initial experimental data is vertical sounding...
ANALYZING EXISTING APPLIED MODELS OF THE IONOSPHERE FOR CALCULATING RADIO WAVE PROPAGATION AND POSSIBILITY OF THEIR USE FOR RADAR SYSTEMS. I. CLASSIFICATION OF APPLIED MODELS AND THE MAIN REQUIREMENTS IMPOSED ON THEM FOR RADAR AIDS
We review modern HF–X band radars covering over-the-horizon problems. The ionosphere significantly affects wave propagation in all the bands. We describe available correction techniques, which use additional evidence on...
ALFVÉN WAVES: TO THE 80TH ANNIVERSARY OF DISCOVERY
The article is dedicated to the anniversary of the discovery of Alfvén waves. The concept of Alfvén waves has played an outstanding role in the formation and development of cosmic electrodynamics. A distinctive feature o...
GEOMAGNETIC DATA RECOVERY APPROACH BASED ON THE CONCEPT OF DIGITAL TWINS
There is no ground-based magnetic station or observatory that guarantees the quality of information received and transmitted to it. Data gaps, outliers, and anomalies are a common problem affecting virtually any ground-b...
