ResumoThe South American ionospheric behavior during the period from 05 to 10 September 2017 is investigated using data from GNSS network from Continuous Monitoring Brazilian Network (RBMC) and ionosondes available in the Space Weather Brazilian Studying and Monitoring (Embrace) site. The geomagnetic activity was produced by the impact of two Coronal Mass Ejections (CMEs) on the Earth magnetosphere . The first one caused a geomagnetic storm that started at 19:00 UT on 07 September and reached the maximum at 02:00 UT on 08 September with DST Index of -142 nT (Intense Storm), KP index 8 and Auroral index 1500 nT. During the recovering phase of this storm another CME arrived at 11:00 UT on 08 September increasing the geomagnetic activity, with Dst reaching -122 nT at 15:00 UT. The Vertical Total Electron Content (VTEC) measured at different latitudes shows a distinct ionospheric response to each storm phase. During the onset main phase of the geomagnetic storm on 7 September VTEC increased at equatorial latitudes during afternoon, and after sunset shows another increase as consequence of electricfield associated with the evening Pre-reversal Enhancement (PRE). In association with the intensification of magnetic storm on 8 September, the VTEC shows an increase during sunrise and the fountain effect was intensified. The results shows that during the first hours of the main phase geomagnetic storm the ionospheric response was mainly affected by the prompt penetration electric fields (PPEFs), being a combination of PPEF and dynamo effects afterwards.
