Variations of total electron content during a magnetic storm
Main Article Content
Abstract
The variations of Total Electron Content (TEC) are analysed during a geomagnetic storm, from measurements of ionospheric delay in code and phase, with the satellites of the Global Positioning System (GPS) at Tucumán, Argentina.
The variations of TEC in April 1997 present high values, compared with averages values of previous years, reaching a value of Kp=7 - on April 11, 1997.
The TEC values exceed by 30% the average values for quiet days for the same time of year.
