Popis: This paper aims to investigate the effect of geomagnetic storms (categorized as intense and moderate) on the fluctuations of Total Electron Content (TEC) in the ionosphere. The TEC obtained from ground-based GPS receivers is utilised to observe the effect of geomagnetic storm activity. The TEC data from an equatorial station, namely Libreville (NKLG) station (0.4162° N, 9.4673° E) for the years 2011 and 2013 were processed. The fluctuations of TEC during intense and moderate storm periods are related to the geomagnetic storms. The TEC perturbation during storms indicates the presence of plasma uplift due to eastward penetration of electric fields at the equatorial station.
