The magnetic structure of the Venus magnetotail has been measured using 9 seasons of Pioneer Venus measurements in the distant wake region. The magnetotail region is about 4 Venus radii wide and about 3.2 Venus radii high at 12 Venus radii behind the planet. The tail contains about 2.3 Megawebers of flux, much of which closes across the tail. The J x B

Particle dynamics and currents in the magnetotail
Astrophysics and Space Science, 1988This paper is a brief summary of our studies of magnetotail phenomena, based on the motion of charged particles and on electric currents. Theory and satellite data have been used together to obtain quantitative understanding.

Undoubtedly, the most lively manifestation of the dynamic nature of the earth’s magnetosphere is the auroral break-up. The magnetospheric phenomena that are associated with this explosive release of energy have been the aim of intense research efforts in recent years, and the term magnetospheric substorm has been introduced to designate these phenomena

Currents in the Earth's magnetotail
1984Currents in the earth's magnetotail are detected with the plasma instrumentation on board the ISEE-1 spacecraft. Field-aligned currents directed into and out of the ionosphere are found in the boundary layer of the plasma sheet. Typical current densities are in the range of 5 x 10-9 to 5 x 10-8 A/m2.

The Earth's Dynamic Magnetotail
Space Science Reviews, 2000Geomagnetic field lines that are stretched on the nightside of the Earth due to reconnection with the interplanetary magnetic field constitute the Earth's magnetotail. The magnetotail is a dynamic entity where energy imparted from the solar wind is stored and then released to generate disturbance phenomena such as substorms. This paper gives an updated

Ion streams in the magnetotail
Journal of Geophysical Research: Space Physics, 1981Ion mass spectrometer observations of low‐temperature streaming plasmas in the earth's magnetotail are reported. Measurements in the energy per charge range 0 ≤E/q ≤17 keV/e were made at geocentric radial distances <23 RE from the ISEE 1 spacecraft.

Relaxation of magnetotail plasmas
Journal of Geophysical Research: Space Physics, 1987A quasi‐thermodynamic model is presented for the relaxation of magnetotail plasmas during substorms, followed by quiet times. It is proposed that the plasma relaxes to a state of low‐potential energy subject to a small number of global constraints.

Substorm dynamics in the magnetotail
Physica Scripta, 1998The large-scale dynamic evolution of the magnetotail in relation to substorms is most commonly understood and described in terms of magnetic reconnection, neutral line formation, and plasmoid ejection into the distant tail, as well as current disruption and diversion in the inner tail.

On the complexity of the Earth’s magnetotail
AIP Conference Proceedings, 2007The Earth’s magnetotail dynamics shows several features that resemble those of a complex system. Here, after a brief review of some recent results and findings pointing towards the occurrence of dynamical complexity, we introduce a simple fully stochastic model for the statistical features of the magnetic field fluctuations in a quiet magnetotail ...
