On the Magnetosphere‐Ionosphere Coupling During the May 2021 Geomagnetic Storm
On 12 May 2021 the interplanetary doppelgänger of the 9 May 2021 coronal mass ejection impacted the Earth's magnetosphere, giving rise to a strong geomagnetic storm.

Identification of the different magnetic field contributions during a geomagnetic storm in magnetospheric and ground observations [PDF]
We used the empirical mode decomposition (EMD) to investigate the time variation of the magnetospheric and ground-based observations of the Earth's magnetic field during both quiet and disturbed periods.

Monitoring of magnetospheric parameters based on cosmic ray effects in August 2018
Using data (uncorrected for the temperature effect) from the global network of neutron monitors (GNNM), along with data from the Yakutsk muon telescope complex and the muon hodoscope URAGAN (Moscow), we have applied a modified spectrographic global ...

Advances made in determining magnetospheric current systems [PDF]
One of the important purposes of the discipline of geomagnetism is to determine how the electric current systems that cause geomagnetic disturbances develop and understand their driving processes, in terms of the solar wind‐magnetosphere interaction. Researchers in geomagnetism have made important progress by combining ground‐based and satellite‐based ...

Creation of the substorm current wedge through the perturbation of the directly driven current system: a new model for substorm expansion [PDF]
The past four decades have seen a considerable amount of research on the study of magnetospheric substorms, and over most of these years the expansive phase of the substorm has been associated with the development of a three dimensional current system

Surface conductivity of Mercury provides current closure and may affect magnetospheric symmetry [PDF]
We study what effect a possible surface conductivity of Mercury has on the closure of magnetospheric currents by making six runs with a quasi-neutral hybrid simulation.

Two-dimensional current-carrying plasma sheet in the near-Earth geomagnetic tail region:
a quasi-stationary evolution [PDF]
A problem concerning stationary configurations of an inhomogeneous, current-carrying, two-dimensional plasma sheet as the solution of the Grad–Shafranov equation with boundary conditions given on cross-sheet profiles at the  ...

An increase in geomagnetically induced currents (GICs) is an inevitable result of geomagnetic field disturbances, and is harmful to the power grid, in particular, at high latitudes.

The role of the Hall effect in the global structure and dynamics of planetary magnetospheres: Ganymede as a case study [PDF]
We present high resolution Hall MHD simulations of Ganymede's magnetosphere demonstrating that Hall electric fields in ion-scale magnetic reconnection layers have significant global effects not captured in resistive MHD simulations. Consistent with local

Magnetodisc modelling in Jupiter's magnetosphere using Juno magnetic field data and the paraboloid magnetic field model [PDF]
One of the main features of Jupiter's magnetosphere is its equatorial magnetodisc, which significantly increases the field strength and size of the magnetosphere. Analysis of Juno measurements of the magnetic field during the first 10 orbits covering the
