STATISTICAL PROPERTIES OF AURORAL KILOMETER RADIATION: BASED ON ERG (ARASE) SATELLITE DATA
Journal Title: Solar-Terrestrial Physics - Year 2021, Vol 7, Issue 1
Abstract
In this work, we have studied the signals of auroral kilometer radiation (AKR) from sources in the auroral regions of the Northern and Southern hemispheres simultaneously recorded by one satellite. We have carried out a detailed statistical analysis of more than 20 months of continuous AKR measurements made by the ERG satellite (also known as Arase). This made it possible to confirm the previously obtained results on the location of AKR sources and seasonal changes in the radiation intensity. Open questions about the processes in the AKR source can be solved using data on the radiation pattern under various geomagnetic conditions. To answer these questions, we have estimated the cone angle of directional diagrams in the dusk and dawn sectors of Earth’s magnetosphere.

IONOSPHERIC RESPONSE TO THE PASSAGE OF TYPHOONS OBSERVED BY SUBIONOSPHERIC VLF RADIO SIGNALS
The response of the lower ionosphere to the passage of several dozen typhoons has been studied using a regional network of VLF stations in the Russian Far East. The experimental data presented in all cases clearly demons...
Ponderomotive redistribution of heavy ions along a magnetic field line
We set up the problem of ponderomotive separation and acceleration of ions with different charge-to-mass ratios under the influence of Alfvén waves, which constantly exist in the magnetosphere in the form of geomagnetic...
FINE STRUCTURE EVENTS IN MICROWAVE EMISSION DURING SOLAR MINIMUM
The solar minimum is a period with a relatively smaller number of sunspots and solar eruptions, and has been less studied before. Since the radio signal rapidly responds to the change of solar plasma and magnetic field,...
TOPSIDE IONOSPHERE DURING SOLAR COSMIC RAY BURSTS AND FORBUSH DECREASES IN GALACTIC COSMIC RAYS
The paper considers the behavior of the upper ionosphere at heights of the F2 layer during Forbush decreases in galactic cosmic rays (GCR FDs) and solar cosmic ray (SCR) bursts. We use the results of long-term continuous...
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...
