Unveiling the combined effects of neutral dynamics and electrodynamic forcing on dayside ionosphere during the 3–4 February 2022 “SpaceX” geomagnetic storms [PDF]
Scientific Reports, 2023 Geomagnetic storms of G1-class were observed on 3 and 4 February 2022, which caused the loss of 38 out of 49 SpaceX satellites during their launch due to enhanced neutral density.

Longitudinal variation of equatorial electrojet and the occurrence of its counter electrojet [PDF]
Annales Geophysicae, 2017 We examined the longitudinal variability of the equatorial electrojet (EEJ) and the occurrence of its counter electrojet (CEJ) using the available records of the horizontal component H of the geomagnetic field simultaneously recorded in the year 2009 (

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 ...

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

Can lower E-region dust particles be responsible for counter electrojet? [PDF]
Geofísica Internacional, 2008 Ablation of meteors leaves a large number of dust particles of sizes ranging from nanometers to several micrometers in the upper mesospheric region. These dust particles can affect the equatorial E-region conductivities in several ways.
