Conclusions

•
•
•
•

•

Small-scale ionospheric anomalies, mostly positive and having different intensities, were isolated In
moments of solar flares and particle emissions.
Geomagnetic disturbances with greatest intensity occurred during periods of significant increase in thesolar wind speed
Electron density was significantly reduced and large-scale negative ionospheric anomalies were formed
during the main phase of geomagnetic storms
Large-scale positive ionospheric anomalies, arising before the start of geomagnetic storms and having
duration of a day or more, were highlighted.
Local fluctuations in cosmic ray variations (both short and longer Forbush effects), which reached its
greatest intensity during periods of significant increase in geomagnetic activity and emergence of largescale negative ionospheric anomalies, were recorded.
Sudden onset of magnetic storm leads to oscillatory processes in atmospheric electricity
