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

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

Longitudinal, seasonal and solar cycle variation in lunar tide influence on the equatorial electrojet [PDF]
Annales Geophysicae, 2017 It has been well documented that the lunar tidal waves can modulate the ionospheric electrodynamics and create a visible influence on the equatorial electrojet (EEJ). The lunar tide influence gets intensified around noon, primarily during new and full

Spatial Development of Strong Storm-Induced Ionospheric Perturbations during 25–27 August 2018
Remote Sensing, 2023 The 25–27 August 2018 geomagnetic storm was the third largest storm in the 24th solar cycle. It was a surprising space event that originated from low-level solar activity.

Variabilities of mesospheric tides and equatorial electrojet strength during major stratospheric warming events [PDF]
Annales Geophysicae, 2009 The present study demonstrates the relationship between the high latitude northern hemispheric major sudden stratospheric warming (SSW) events and the reversal in the afternoon equatorial electrojet (EEJ), often called the counter-electrojet (CEJ ...

The field of the equatorial electrojet from CHAMP data [PDF]
Annales Geophysicae, 2006 We apply a simple linear transform, the along-track second derivative, to four years of scalar and vectorial data from the CHAMP satellite. This transform, reminiscent of techniques used in the interpretation of aeromagnetic surveys, is applied either

Secondary irregularities in the equatorial electrojet [PDF]
Journal of Geophysical Research, 1967 Although the two-stream instability theory, discussed by Farley, has been quite successful in accounting for many observed features of the plasma-wave irregularities produced in the equatorial electrojet, increased equipmental sensitivity and improved experimental techniques of observing the power spectrum of radio echoes from the electrojet have ...

Variations of the peak positions in the longitudinal profile of noon-time equatorial electrojet
Earth, Planets and Space, 2020 In this study, the seasonal variations of the EEJ longitudinal profiles were examined based on the full CHAMP satellite magnetic measurements from 2001 to 2010. A total of 7537 satellite noon-time passes across the magnetic dip-equator were analyzed.

Equatorial electrojet at African longitudes: first results from magnetic measurements [PDF]
Annales Geophysicae, 1998 In the framework of the French participation in the International Equatorial Electrojet Year (IEEY), ten magnetotelluric stations were installed between November 1992 and November 1994 along a 1200-km-long meridian profile, between Lamto (latitude 6.2°
