IONOSPHERIC ANOMALIES OVER BULGARIA DURING TWO GEOMAGNETIC STORMS
Bulgarian Geophysical Journal, 2018, Vol. 41, DOI: https://doi.org/10.34975/bgj-2018.41.2
This paper considers ionospheric anomalies over the territory of Bulgaria during geomagnetic storms – the storm on 5 April 2010 and the event on 9 March 2012. The response of the ionosphere over Bulgaria is represented by data, collected by the ionospheric station in Sofia at NIGGG- BAS. The values of the Total Electron Content (TEC) have been provided by the Center for Orbit Determination of Europe (CODE). The data for variations on Earth magnetic field are received from INTERMAGNET. It was used the station Panagyurishte (PAG) located on the territory of Bulgaria. The impact of ionospheric anomalies on radio communication on frequencies in shortwave and satellite navigation is also analyzed.
