The afternoon counter-electrojet current system along the 75°E meridian during the IEEY

open access: yesEarth, Planets and Space, 2017
In the present study, the technique of principal component analysis (PCA) is applied to analyze the hourly mean values of geomagnetic field components D, H, and Z along an Indo-Russian chain of stations during the International Equatorial Electrojet Year

Meridional Currents of the Equatorial Electrojet

open access: yesGeophysical Research Letters
The equatorial electrojet (EEJ) is a prominent eastward geomagnetic current flowing at the dayside magnetic dip equator, peaking just before noon. Associated meridional currents also flow perpendicular to the main current, predicted through modeling and ...

Meridional equatorial electrojet current in the American sector [PDF]

open access: yesAnnales Geophysicae, 1999
Huancayo is the only equatorial electrojet station where the daytime increase of horizontal geomagnetic field (H) is associated with a simultaneous increase of eastward geomagnetic field (Y). It is shown that during the counter electrojet period when ∆

Prompt penetration effects on Equatorial Electrojet from the Indian sector

open access: yesEarth, Planets and Space, 2023
The morphology of prompt penetration effects (PP) in the Equatorial Electrojet (EEJ) at Vencode (VEN, Geomagnetic latitude 0.29ºN) was studied using 5-min samples of EEJ and interplanetary Ey component data from 2011 to 2015.

Observations of equatorial ionization anomaly over Africa and Middle East during a year of deep minimum [PDF]

open access: yesAnnales Geophysicae, 2017
In this work, we investigated the veracity of an ion continuity equation in controlling equatorial ionization anomaly (EIA) morphology using total electron content (TEC) of 22 GPS receivers and three ground-based magnetometers (Magnetic Data ...

Morphological aspects of a new type of counter electrojet event [PDF]

open access: yesAnnales Geophysicae, 1999
The study describes the time and space morphologies of a rather new type of counter electrojet event on the basis of data from the excellent chain of magnetic and ionospheric observatories along the Indo-Russian longitude sector.

Electrodynamical response of the Indian low-mid latitude ionosphere to the very large solar flare of 28 October 2003 – a case study [PDF]

open access: yesAnnales Geophysicae, 2009
The electrodynamic effects on the low-mid latitude ionospheric region have been investigated using GPS (global positioning system) data, ionosonde data and ΔH values, during the very large solar flare (X17.2/4B) of 28 October 2003.

Asymmetries in the equatorial electrojet around N-E Brazil sector [PDF]

open access: yesAnnales Geophysicae, 2009
The paper examines the data of geographic northward (X), eastward (Y) and vertical (Z) components of the magnetic field from a dense array of 26 vector magnetometers operated in N-NE Brazil from November 1990 to March 1991.

Equatorial electrojet as part of the global circuit: a case-study from the IEEY [PDF]

open access: yesAnnales Geophysicae, 1998
Geomagnetic storm-time variations often occur coherently at high latitude and the day-side dip equator where they affect the normal eastward Sq field. This paper presents an analysis of ground magnetic field and ionospheric electrodynamic data related
