Double Auroral Undulation During the Main Phase of the May 10–11, 2024 Storm
AGU Advances, Volume 6, Issue 4, August 2025.Abstract We report the discovery of a new type of aurora, namely, double auroral undulation that occurred simultaneously on both equatorward and poleward edges of the duskside auroral oval during the main phase of the May 10–11, 2024 superstorm. Whereas the equatorward auroral undulation (EAU) has been frequently observed and well known, the poleward ...

Random Forest Model of Ultralow‐Frequency Magnetospheric Wave Power
Earth and Space Science, 2020 Models of magnetospheric ultralow‐frequency (ULF) waves can be used to study wave phenomena and to calculate the effect of these waves on the energization and transport of radiation belt electrons.

Main statistical properties of hectometric continuum radiation in near-Earth space
Solar-Terrestrial Physics, 2023 In this work, we have studied the recently discovered hectometric continuum radiation in near-Earth plasma. We have carried out a detailed statistical analysis of the occurrence of a hectometric continuum near Earth at distances 1.1–2 Re, where Re is the

AGU Advances, Volume 6, Issue 4, August 2025.Abstract Auroral Kilometric Radiation (AKR), the dominant radio emission from Earth, has been extensively studied, though previous analyses were constrained by limited spacecraft coverage. This study utilizes long‐term observations from Polar, Wind, and Arase spacecraft to generate comprehensive global AKR occurrence rate maps, revealing a high ...

Warping modes in discs around accreting neutron stars
, 2009 The origin and stability of a thin sheet of plasma in the magnetosphere of an accreting neutron star is investigated. First the radial extension of such a magnetospheric disc is explored.

Geophysical Research Letters, Volume 52, Issue 14, 28 July 2025.Abstract Observations from the Juno spacecraft near the M‐shells of the Galilean moons have identified alternating enhancements and reductions of particle fluxes at discrete energies. These banded structures were previously attributed to bounce resonance between particles and standing Alfvén waves generated by moon‐magnetospheric interactions. Here, we

Statistical Properties of Molecular Ions in the Ring Current Observed by the Arase (ERG) Satellite
Geophysical Research Letters, 2019 Molecular ions in the magnetosphere can be a tracer of fast ion outflows from the deep ionosphere. Statistical properties of molecular ions (O2+/NO+/N2+) in the ring current are investigated based on ion composition measurements (

Response of convection electric fields in the magnetosphere to IMF orientation change [PDF]
, 2009 [1] The transient response of convection electric fields in the inner magnetosphere to southward turning of the interplanetary magnetic field (IMF) is investigated using in‐situ electric field observations by the CRRES and Akebono spacecraft.

Eos, Transactions American Geophysical Union, 1968 The magnetospheric substorm is perhaps the most widely known yet most poorly understood facet of magnetospheric disturbances. It is generally agreed that the substorm results from an explosive conversion of magnetic energy generated by the interaction between the solar wind and the magnetosphere.
