Geophysical Research Letters, 2022 Throat auroras have been suggested to correspond to magnetopause indentations, but how such indentations can be generated is an open question. Using coordinated magnetopause in situ and two‐dimensional auroral imaging observations, we showed that a ...

Electron Bulk Heating at Saturn's Magnetopause [PDF]
Journal of Geophysical Research: Space Physics, 2020 Abstract Magnetic reconnection at the magnetopause (MP) energizes ambient plasma via the release of magnetic energy and produces an “open” magnetosphere allowing solar wind particles to directly enter the system. At Saturn, the nature of MP reconnection remains unclear.

Global MHD Simulations of Neptune's Magnetosphere [PDF]
, 2016 A global magnetohydrodynamic (MHD) simulation has been performed in order to investigate the outer boundaries of Neptune's magnetosphere at the time of Voyager 2's flyby in 1989 and to better understand the dynamics of magnetospheres formed by highly ...

The magnetopause shape and location: a comparison of the Interball and Geotail observations with models [PDF]
Annales Geophysicae, 2002 A number of magnetopause models have been developed in the course of last three decades. We have chosen seven of them and tested them using a fresh set of magnetopause crossings observed by Interball-1, Magion-4, and Geotail satellites.

IMPALAS: Investigation of MagnetoPause Activity using Longitudinally-Aligned Satellites—a mission concept proposed for the ESA M3 2020/2022 launch [PDF]
, 2012 The dayside magnetopause is the primary site of energy transfer from the solar wind into the magnetosphere, and modulates the activity observed within the magnetosphere itself.

Extreme geomagnetic disturbances due to shocks within CMEs [PDF]
, 2015 We report on features of solar wind-magnetosphere coupling elicited by shocks propagating through coronal mass ejections (CMEs) by analyzing the intense geomagnetic storm of 6 August 1998.

Statistical survey of day-side magnetospheric current flow using Cluster observations: magnetopause [PDF]
Annales Geophysicae, 2017 We present a statistical survey of current structures observed by the Cluster spacecraft at high-latitude day-side magnetopause encounters in the close vicinity of the polar cusps.

Ion Larmor radius effects near a reconnection X line at the magnetopause: THEMIS observations and simulation comparison [PDF]
, 2016 We report a Time History of Events and Macroscale Interactions during Substorms (THEMIS-D) spacecraft crossing of a magnetopause reconnection exhaust ~9 ion skin depths (di) downstream of an X line. The crossing was characterized by ion jetting at speeds

Geophysical Research Letters, 1996 A novel method is described for reconstruction of two‐dimensional current‐layer structures from measurements taken by a single spacecraft traversing the layer. In its present form, the method is applicable only to 2D magneto‐hydrostatic structures that are passively convected past the observing spacecraft. It is tested on a magnetopause crossing of the

Geophysical Research Letters, 2022 Juno's flyby of Ganymede on 7 June 2021, provides a unique opportunity to explore the moon's magnetosphere. By means of Magnetometer (MAG) observations and a hybrid numerical simulation, we provide a global description of this environment and analyze the
