Ionospheric response to the 26 August 2018 geomagnetic storm along 280° E and 316° E in the South American sector
This paper studies the response of the ionospheric parameters critical frequency (foF2), their height (hmF2), and Total Electron Content (TEC) at mid, low, and near-equatorial latitudes of the South American sector during the intense geomagnetic storm of 26 August 2018. The ionospheric response at the beginning of the main phase was different depending on latitude (in general, there were decreases in foF2 at near-equatorial and low latitudes and small increases at mid-latitudes). During the recovery, positive storm effects i ...

Effects on the equatorial and low latitude thermosphere and ionosphere during the 19--22 December 2015 geomagnetic storm period
In this paper, the critical frequency of F2 layer (foF2) and their peak height (hmF2) recorded at equatorial and low latitude stations of the South American sector were analyzed during the 19\textendash22 December 2015 geomagnetic storm period. We have observed initially decreases of foF2 at equatorial and low latitudes over the North crest of the equatorial ionization anomaly (EIA) and almost no effect over the South crest. These initial negative storm effects can be fully explained by the penetration of a westward elect ...

Consequences of a solar wind stream interaction region on the low latitude ionosphere: event of 7 October 2015
In this article, we present a study of the perturbations occurring in the Earth’s environment on 7 October 2015. We use a multi-instrument approach, including space and ground

Ionospheric Response to the Magnetic Storm of 22 June 2015
A global study is made of the response of the total electron content of the ionosphere (TEC) to the geomagnetic storm occurred on 22 June 2015 (one of the strongest geomagnetic storms of the current Solar Cycle 24). Using data from 44 sites, a hemispheric comparison is made by considering high latitudes (\>\ 50\textdegree), middle latitudes (30\textdegree\textendash50\textdegree) and low latitudes (30\textdegreeN\textendash30\textdegreeS). The main features observed were: increases in TEC at high latitudes prior t ...
