Jovian Auroral Proton Precipitation

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The total power of the Jovian aurora is about 1013–1014 W with ultraviolet emission observed in the Lyman and Werner bands of molecular hydrogen. X‐ray, radio, and infrared emissions have also been observed. The Jovian Auroral Distributions Experiment and the Jovian Energetic Particle Detector Instrument onboard the Juno spacecraft, orbiting ...

Low Frequency Extensions of Cyclotron Maser Instability‐Generated Radio Emission: A Statistical View From Cassini at Saturn

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The Cassini spacecraft spent 13 years orbiting Saturn, quasi‐continuously measuring Saturn's radio emissions. One of the key elements of the radio spectrum at Saturn is the Saturn Kilometric Radiation (SKR), and several studies have been written on events called Low Frequency Extensions (LFEs) which represent strong, continuous extensions of ...

Reconstructing Europa's Atmosphere From H2+ ${\mathbf{H}}_{\mathbf{2}}^{+}$ Pickup Ions Detected During the Juno PJ45 Flyby

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract We use a suite of single‐species (H2 ${\mathrm{H}}_{2}$) and multispecies (H2+O2+H+O ${\mathrm{H}}_{2}+{\mathrm{O}}_{2}+\mathrm{H}+\mathrm{O}$) Direct Simulation Monte Carlo models of Europa's atmosphere to interpret the H2+ ${\mathrm{H}}_{2}^{+}$ pickup ions detected by Juno at distances beyond 2 $2$ Europa radii RE $\left({R}_{E}\right ...

Quantitative Assessment of Geographic Control of December Solstice EIA Crest Shifts Over Southeast Asia Under Low Solar Activity

open access: yesSpace Weather, Volume 24, Issue 8, August 2026.
Abstract This study quantitatively assesses the drivers of the Equatorial Ionization Anomaly (EIA) morphology and latitudinal shifts over Southeast Asia during the December solstice. We use a 27‐year ionospheric data set (1998–2024) of total electron content (TEC) and F2‐layer peak electron density (NmF2) under geomagnetically quiet conditions.

An Ionospheric Storm Scale Index Based on TEC: Comparative Analysis for China Region

open access: yesSpace Weather, Volume 24, Issue 8, August 2026.
Abstract Defining a standardized ionospheric storm scale is challenging given the ionosphere's inherent complexity and susceptibility to multiple driving factors. In this study, a novel ionospheric storm scale (ISS) index is developed based on statistical analysis of total electron content (TEC) data from 257 ground‐based GNSS stations across China ...
