We present the results of observations of traveling ionospheric disturbances (TIDs) based on the data of the operation of the network of chirp oblique sounding stations of the ionosphere on 18–19 December 2019. For observations, four stations of th

Modern society replies on the ionosphere for technology such as radio navigation and telecommunications. However, this is not a static environment and its characteristics can be affected by solar phenomena such as coronal mass ejections (CMEs) and hi

We present preliminary results of a study the solar eclipse effect (on August 11, 2018) to the characteristics of HF signals according to oblique sounding of the ionosphere on extended radio paths in the Eurasian region.

In this report we present an attempt to find a characteristic set of the space weather parameters allowed to identify the dominant physical connections. This study is based on the data of vertical and oblique sounding of the ionosphere in 2015-2016.

We compare long-period pulsations of the horizontal component of the geomagnetic field at intervals that precede extreme solar flares. To this end, we use the wavelet–skeleton technique to process the geomagnetic field disturbances recorded at magn

The opportunity of development the short-term forecasting technique of geoeffective solar flares is presented in this study. This technique is based on the effect of growth the fluctuations of horizontal component of geomagnetic field before the sola

In this report we present a possible scheme of short-term CME detection forecasting developed on the basis of statistical analysis of solar radio emission regularities prior to “isolated” solar Coronal Mass Ejections registered in 1998, 2003, 200

We consider sporadic radio emission which precedes recording of geoeffective coronal mass ejections, using the data of broadband patrol observations of the Sun in the centimeter-, decimeter-, and meter-wave ranges in some periods of the XXIst–XXIII

We consider the phenomena observed in the microwave radiation emitted by the Sun during a two-hour period, which precedes the time when the coronagraph records coronal mass ejections. The data of 24-h patrol observations of centimeter- and decimeter-

Data on the complex of wave and spectral phenomena in the sporadic microwave emission that are associated with the formation and initial propagation of coronal mass ejections (CMEs) in the solar atmosphere are presented. Their characteristic time int
