Global MHD simulations of Saturns's magnetosphere at the time of Cassini approach [PDF]

, 2005
We present the results of a 3D global magnetohydrodynamic simulation of the magnetosphere of Saturn for the period of Cassini's initial approach and entry into the magnetosphere. We compare calculated bow shock and magnetopause locations with the Cassini

Quasi 6‐Day Wave Variability in the Thermosphere and Ionosphere: Observations and Modeling

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Satellite observations of the upper mesosphere and lower thermosphere from TIMED‐SABER and ICON‐MIGHTI reveal a clear Quasi 6‐Day Wave (Q6DW) event in the winds and temperatures in this region. This Q6DW event persists across multiple data sets throughout the middle‐to‐upper thermosphere and the F‐region ionosphere, including GOLD disk ...

Interplanetary magnetic field rotations followed from L1 to the ground : the response of the Earth's magnetosphere as seen by multi-spacecraft and ground-based observations [PDF]

, 2011
A study of the interaction of solar wind magnetic field rotations with the Earth's magnetosphere is performed. For this event there is, for the first time, a full coverage over the dayside magnetosphere with multiple (multi)spacecraft missions from dawn ...

Analytical Modeling of Hot Ion Interchange Injections in Saturn's Magnetosphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Cassini's CHarge Energy Mass Spectrometer (CHEMS) instrument collected energetic plasma data from 2004 to 2017, including hundreds of observations of small‐scale nearly dispersionless “local” injection events into the inner magnetosphere. This study assesses whether these interchange‐like injections are a channel‐like structure still connected

Statistical Scale Analyses of a Diurnal Periodicity in Auroral Kilometric Radiation, Observed by Wind/WAVES

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract The Earth's strongest natural radio emission is Auroral Kilometric Radiation (AKR), which is correlated with auroral intensity, and is a barometer for space weather. AKR is generated by the electron cyclotron maser instability, with sources on auroral field lines. Previous work on AKR and radio emissions from other planets (or stars) points to

On the problem of the influence of the magnetosphere disturbance onto the rotational regime of the Earth

Учёные записки Казанского университета: Серия Физико-математические науки, 2018
The earlier hypothesis on solar control (through changes of global magnetic disturbance in the magnetosphere) of the Earth rotational regime has been confirmed on the basis of the analysis of heliogeophysical data for the period of 1927 to 2017.

Modeling Kinetic Reconnection Onset in Global Magnetospheric Simulations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract We investigate the onset of magnetic reconnection in Earth's magnetotail using a coupled magnetohydrodynamic with embedded particle‐in‐cell (MHD‐EPIC) model, which self‐consistently links global magnetospheric dynamics to electron‐scale kinetic processes. Unlike standalone kinetic simulations with idealized boundary conditions, reconnection in

A Magnetospheric Source for Near‐Planet Whistler‐Mode Waves at Venus

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract The presence or absence of lightning in the atmosphere of Venus has important implications for atmospheric chemistry, potential chemical signatures of life, identifying volcanic activity, and quantifying potential hazards to future exploration missions.

Neural Network Imputation of the Pitch‐Angle‐Resolved Medium‐Energy Electron Flux Data in LEO

Space Weather, Volume 24, Issue 9, September 2026.
Abstract Pitch‐angle‐resolved electron flux data are crucial for investigating variations in electron flux within the magnetosphere and the underlying mechanisms, such as radial diffusion and wave‐particle interactions. The Medium‐Energy Electron Detector (MEED) onboard the Fengyun‐3E (FY‐3E) satellite in Low Earth Orbit (LEO) provides 18‐directional ...
