Solar Cycle and Seasonal Distribution of Geomagnetic Storms with Sudden Commencement
(Canadian Center of Science and Education, 2014-02)
In this brief paper the seasonal and solar cycle distribution of storms with sudden commencement is presented. A correlation between the number of geomagnetic storms by month and monthly sunspot numbers is observed. Also, ...
Conseqüências de uma tempestade geomagnética no posicionamento relativo com receptores GPS de simples freqüência
The error associated with the ionosphere depends on Total Electron Content (TEC) of the ionosphere. The geomagnetic field exerts strong influence in the TEC variation, because it controls the movement of the electrons. ...

Investigation of ionospheric response to two moderate geomagnetic storms using GPS–TEC measurements in the South American and African sectors during the ascending phase of solar cycle 24
The responses of the ionospheric F region using GPS–TEC measurements during two moderate geomagnetic storms at equatorial, low-, and mid-latitude regions over the South American and African sectors in May 2010, during the ...
Some ionospheric storm effects at an antarctic station
In this paper, the ionospheric response of a high latitude station to some intense geomagnetic storms occurred in 2000 and 2001 is analyzed. For that, data of the critical frequency of the F2-layer foF2 and the virtual ...
