Is the Magnetic Field Line Curvature Really Important for Energetic Electron Losses From the Radiation Belt?

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Recently, Hua et al. (2026, https://doi.org/10.1029/2025GL120881) combined observations during a 4‐day storm period with numerical simulations and concluded that the abrupt electron loss in the field‐line‐curvature scattering (FLCS) region played a leading role in shaping the outer boundary of radiation belt (RB); the authors conjectured that ...

Solar Wind-Magnetosphere-Ionosphere Coupling and the Electric Circuit ofGeomagnetic Storms [PDF]

Intense solar wind driving of the terrestrial magnetosphere, can result in geomagnetic storms, where the morphology and behaviour of the magnetosphere undergoes complex changes. This thesis studies storm-time changes in the electric current systems which

MMS Observations of the Energetic Particles Within Kelvin‐Helmholtz Waves at the Boundary of the 10 May 2024 Coronal Mass Ejection (CME)

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract On 10 May 2024, Earth was hit by a CME that drove the largest geomagnetic storm in 20 years. Multi‐spacecraft observations previously showed that the ∼100 nT north‐south IMF bz ${b}_{z}$ variation was driven by Kelvin‐Helmholtz waves with wavelength ∼250 RE ${R}_{E}$ and reconnection jets in the ±z $\pm z$‐direction (Nykyri, 2024a, https://doi.

A statistical analysis of the location and width of Saturn's southern auroras [PDF]

, 2006
peer reviewedA selection of twenty-two Hubble Space Telescope images of Saturn's ultraviolet auroras obtained during 1997-2004 has been analysed to determine the median location and width of the auroral oval, and their variability.

Looking Into Pulsar Magnetospheres [PDF]

Astrophysics and Space Science, 2001
AbstractDiffractive and refractive magnetospheric scintillations may allow direct probing of the plasma inside the pulsar light cylinder. The unusual electrodynamics of the strongly magnetized electron-positron plasma allows separation of the magnetospheric and interstellar scattering.

Global Wind Field Reconstruction in the Mesosphere and Lower Thermosphere (MLT) During Geomagnetic Storms by Fusing TIDI and SABER Data: A Generative Adversarial Network (GAN) Approach

Geoscience Data Journal, Volume 13, Issue 3, July 2026.
ABSTRACT The Mesosphere and Lower Thermosphere establish an essential connection between Earth's lower atmosphere and upper atmosphere because wind patterns essential for atmospheric movement also influence energy distribution and chemical movements during geomagnetic storms that disrupt satellite operations and space weather prediction systems.

On the character and distribution of lower-frequency radio emissions at Saturn and their relationship to substorm-like events [PDF]

, 2009
With the arrival of the Cassini spacecraft at Saturn in July 2004, there have been quasi-continuous observations of Saturn kilometric radiation (SKR) emissions.

Impact of Magnetosphere Forcing and Model Resolution on Joule Heating Estimates in WACCM‐X During the 24 August 2005 Storm

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract We investigate the high‐latitude Joule heating in a recently developed high‐resolution configuration of the WACCM‐X whole‐atmosphere model coupled to the MAGE model. Model resolution and geomagnetic forcing effects during the severe (Kp>8) $(Kp > 8)$ geomagnetic storm on 24 August 2005 are analyzed, distinguishing storm peak and recovery ...

Scaling of solar wind e and the AU, AL and AE indices as seen by WIND [PDF]

, 2002
We apply the finite size scaling technique to quantify the statistical properties of fluctuations in AU, AL and AE indices and in the parameter that represents energy input from the solar wind into the magnetosphere. We find that the exponents needed 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.
