Dissipation of field-aligned currents in the topside ionosphere [PDF]

Scientific Reports, 2022
Field-aligned currents (FACs) are electric currents parallel to the geomagnetic field and connecting the Earth’s magnetosphere to the high-latitude ionosphere.

Field-aligned currents in the magnetosphere

Geofísica Internacional, 1991
Las corrientes alineadas con el campo en la magnetosfera fluyen en todas partes, no s6lo a altas 1"-titudes sino también a medianas y bajas. Sin embargo, su detecci6n con satcHites solo ha sido posible en la región por encima de las zonas aurorales.

Sign-Singularity Analysis of Field-Aligned Currents in the Ionosphere

Atmosphere, 2021
Field-aligned currents (FACs) flowing in the auroral ionosphere are a complex system of upward and downward currents, which play a fundamental role in the magnetosphere–ionosphere coupling and in the ionospheric heating.

Transient, small‐scale field‐aligned currents in the plasma sheet boundary layer during storm time substorms [PDF]

Geophysical Research Letters, 2016
We report on field‐aligned current observations by the four Magnetospheric Multiscale (MMS) spacecraft near the plasma sheet boundary layer (PSBL) during two major substorms on 23 June 2015.

Statistical Analysis of Bifurcating Region 2 Field-Aligned Currents Using AMPERE

Frontiers in Astronomy and Space Sciences, 2022
We present a statistical analysis of the occurrence of bifurcations of the Region 2 (R2) Field-Aligned Current (FAC) region, observed by the Active Magnetosphere and Planetary Electrodynamics Response Experiment (AMPERE).

On the Relationship Between Regions of Large‐Scale Field‐Aligned Currents and Regions of Plateau in Plasma Pressure Observed in the Equatorial Plane of the Earth's Magnetosphere

Geophysical Research Letters, 2023
Since the discovery of the large‐scale field‐aligned currents it is widely acknowledged that gaps exist between the Region 1 (R1) and Region 2 (R2) currents in which the current values are relatively small as compared to neighboring regions.

Signatures of field‐aligned currents in Saturn's nightside magnetosphere [PDF]

Geophysical Research Letters, 2009
We report first results of a survey of near‐simultaneous and near‐conjugate magnetic field perturbations observed over Saturn's northern and southern nightside auroral regions on ∼40 periapsis passes of the Cassini spacecraft during 2008. Structured azimuthal fields that are generally anti‐symmetric north and south were observed at auroral latitudes on

Multiscale Features of Magnetic Field Fluctuations and Field-Aligned Currents in the Polar Ionosphere: A Case Study

Universe, 2022
Complexity is a typical feature of space plasmas that may involve the formation of multiscale coherent magnetic and plasma structures. The winding features (pseudo-polarization) of magnetic field fluctuations at different spatial scales are a useful ...

On the structure of field-aligned currents in the mid-altitude cusp [PDF]

Annales Geophysicae, 2006
We analyse two crossings of the polar cusp at mid-altitudes (≈4 RE) by Cluster in order to study the structure of field-aligned currents associated with the injection of magnetosheath plasma.

Online system for analyzing currents in the upper ionosphere according to Swarm satellite data

Solar-Terrestrial Physics, 2023
In this paper, we describe the TeslaSwarm online system [http://aleph.gcras.ru/teslaswarm] for visualizing field-aligned currents in the upper ionosphere, using data from Swarm low-orbit satellites.
