TLDR
In this paper, the results of a rocket borne electric field experiment flown near local midnight from Andenes, Norway have been transformed to an Earth-fixed coordinate system and compared with plasma temperature and density measurements, energetic particle fluxes, and perpendicular electric field variations, to strengthen the earlier conclusion that ∼10 mV/m electric fields existed parallel to the magnetic field line during the flight.About:

Ionosphere-Magnetosphere Coupling
TL;DR: In this article, a review of the electric coupling between the ionosphere and magnetosphere is given, focusing on the mapping of time-dependent electric fields, the effects of Birkeland currents on the magnetospheric plasma convection, and the relation of BIC to ionospheric electric field structures such as field reversals, secondary BICs, and an equivalent electric circuit for the substorm currents in coupled ionosphere-magnetosphere system.

Electric field mapping in the ionosphere at the equatorial plane
TL;DR: In this paper, the relationship between the components of electric field perpendicular to the magnetic field line in the ionosphere and at the equator is computed for dipole and distorted magnetic field models under the assumption that magnetic field lines are electric equipotentials.

The average auroral zone electric field
F. S. Mozer,P. Lucht +1 more
TL;DR: In this article, the authors analyzed the auroral zone electric field data obtained by the flight of 32 balloons between L = 5.4 and L = 8.2 and concluded that important parallel potential drops exist along auroral magnetic field lines or simple conjugacy between the two hemispheres does not exist along such field lines.

Radar observations of electric fields and currents associated with auroral arcs
TL;DR: In this article, the incoherent scatter radar at Chatanika, Alaska, has been used to study electric fields and horizontal currents associated with auroral arcs, and the direction of this field is determined by the directions of the east-west field, which, in all three cases, is westward within the arc.
Journal ArticleDOI
Observed characteristics of auroral forms
TL;DR: In this paper, it was shown that the extended auroral arc is the basic form of the discrete aurora and that strong electric fields, both horizontal and vertical, characterize the discrete and pulsating aurora.

A mechanism for energizing electrons in the magnetosphere
TL;DR: In this article, an electrodynamic heating mechanism is proposed to account for the precipitation of kilovolt energy electrons during an auroral disturbance, given the existence of an electric field transverse to the geomagnetic field caused by space charges in the magnetosphere, currents will flow along the magnetic field connecting the space charges to the conducting ionosphere.

TL;DR: In this article, five Nike-Apache rockets were launched from Kiruna, Sweden, carrying barium release and electron concentration experiments, and the magnitudes of the electric fields varied between 2 and 20 v/km.

Effects of Field-Aligned Currents on the Structure of the Ionosphere
TL;DR: The influence of electric currents along the magnetic field lines on the high-latitude F-layer ionosphere is investigated theoretically in this paper, where it is shown that a current of either sign leads to a reduction of the total electron content and the maximum density, if the charge carriers have to be produced in the ionosphere.

Investigation of the operation of a d.c. electric field detector
TL;DR: In this article, double-lungmuir probe detector systems have been successfully used on three rockets in the past two years to measure quasi-static and a.c. electric fields in the auroral zone ionosphere.
