             abstract = "Coronal mass ejection (CME) occurs when there is an abrupt release 
                         of a large amount of solar plasma, and this cloud of plasma 
                         released by the Sun has an intrinsic magnetic field. In addition, 
                         CMEs often follow solar flares (SF). The CME cloud travels outward 
                         from the Sun to the interplanetary medium and eventually hits the 
                         Earth's system. One of the most significant aspects of space 
                         weather is the ionospheric response due to SF or CME. The 
                         direction of the interplanetary magnetic field, solar wind speed, 
                         and the number of particles are relevant parameters of the CME 
                         when it hits the Earth's system. A geomagnetic storm is most 
                         geo-efficient when the plasma cloud has an interplanetary magnetic 
                         field southward and it is accompanied by an increase in the solar 
                         wind speed and particle number density. We investigated the 
                         ionospheric response (F-region) in the Brazilian and African 
                         sectors during a geomagnetic storm event on September 0710, 2017, 
                         using magnetometer and GPS-TEC networks data. Positive ionospheric 
                         disturbances are observed in the VTEC during the disturbed period 
                         (September 0708, 2017) over the Brazilian and African sectors. 
                         Also, two latitudinal chains of GPS-TEC stations from the 
                         equatorial region to low latitudes in the East and West Brazilian 
                         sectors and another chain in the East African sector are used to 
                         investigate the storm time behavior of the equatorial ionization 
                         anomaly (EIA). We noted that the EIA was disturbed in the American 
                         and African sectors during the main phase of the geomagnetic 
                         storm. Also, the Brazilian sector was more disturbed than the 
                         African sector.",
