Direct Radiation Belt Injections and Their Auroral Counterparts

Geophysical Research Letters
We present a case study of a moderate geomagnetic storm, which exhibits an abrupt relativistic enhancement in the heart of the radiation belt accompanied by low‐latitude purple auroral emission.

A Machine Learning‐Based Model of Three‐Dimensional Ion Fluxes in the High‐Altitude Earth's Northern Cusp

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Magnetic reconnection at the dayside magnetopause is the primary pathway for transferring mass, momentum, and energy from the solar wind into the terrestrial magnetosphere. Previous studies have shown that the spatiotemporal dynamics of dayside magnetic reconnection can be inferred remotely from properties of Earth's cusps, specifically their ...

KITSAT-1 Cosmic Ray Experiment-Initial Results [PDF]

Journal of Astronomy and Space Sciences, 1993
The KITSAT-1 was successfully launched on August 11, 1992, into a near circular, 1300-km-high orbit with an 66 deg inclination. The satellite carries a solid state detector module to measure the high energy particle flux originating mostly from the inner

Faint Diffuse 557.7‐nm Emissions Equatorward of the Auroral Oval: Conjugate Observations by Ground Airglow Imagers and the Arase Satellite

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract At subauroral latitudes, discrete auroras, such as strong thermal emission velocity enhancement and stable auroral red arcs, have been extensively studied. On the other hand, diffuse emissions at subauroral latitudes have not been studied well.

Combining Van Allen Probes and CubeSat Observations to Estimate Storm‐Time Maximum Outer Radiation Belt Electron Fluxes

Space Weather
Understanding and forecasting extreme radiation belt electron fluxes has been a major goal in space weather since their discovery in 1958. In this study, by combining electron flux data from multiple satellite missions in different orbits, including Van ...

Elastic Properties of Titan Tholins Revealed by Brillouin Spectroscopy

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Titan tholins, complex organic solids synthesized by simulating photochemical processes in Titan's atmosphere, are widely regarded as analogs to organic surface materials on the Saturnian moon. Their mechanical properties are critical for understanding the evolution of Titan's geomorphology and crustal layering.

Radial diffusion coefficient for the inner part of the Earth's electron radiation belt [PDF]

, 2008
The radiation belts are the region that energetic charged particles are trapped by Earth’s magnetic field. The radiation belts have been observed by a lot of satellites and researched by theoretical approach since the discovery of it.
