Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.Abstract We present large‐scale simulations of energetic neutral atom (ENA) emissions at Uranus from a spacecraft viewpoint. Models of magnetic field, extended hydrogen exosphere, moon‐sourced neutral tori, and proton radiation belt are implemented into a simulator to evaluate the production of ENAs for L $L$ = 1–15.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.Abstract The objective of the present study is to investigate solar wind‐magnetosphere‐ionosphere coupling (SWMIC) under intense external driving in terms of dayside ground magnetic disturbances. Dayside magnetic reconnection drives a region‐1 sense current system, the SWMIC current system.

Geoelectric Field Caused by Flux Transfer Events in an Ionosphere‐Coupled Vlasiator Simulation
Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.Abstract We report on the relationship between flux transfer events (FTEs) at Earth's magnetopause and the geoelectric field that is induced near the FTEs' magnetic footpoints. We study this system using the global hybrid‐Vlasov code Vlasiator, which has recently been extended to model ionospheric physics.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.Abstract The Madden–Julian Oscillation (MJO), a recurring intraseasonal (30–96 days) disturbance in the troposphere, strongly influences the E‐region and F‐region ionosphere through its modulation of atmospheric tides. Among these, the diurnal eastward wave number 3 (DE3) tide, driven by MJO‐modulated latent heating, carries MJO signals upward into the

Temporal Variability of Saturn's H2 Dayglow and Northern Aurora Observed by Hisaki and Cassini
Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.Abstract Ultraviolet (UV) emissions from molecular hydrogen in Saturn's atmosphere consist of bright auroral emission over the poles and disk‐wide airglow. The dayside disk emits substantial intensities (dayglow) previously detected by various instruments.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.Abstract We present the first comprehensive multi‐instrument climatological study of quiet‐time equatorial F‐region vertical plasma drifts across South America, a region where the magnetic declination angle varies significantly. Our analysis of well‐established long‐term ground‐based data sets from the Jicamarca incoherent scatter radar spanning 1968 ...

Jupiter's Auroral Ionosphere: Hybrid Monte Carlo, Auroral Spectrum and Conductivity Modeling
Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.Abstract We present a new model of auroral precipitation and associated phenomena at Jupiter, called the Jupiter Auroral Ionosphere Code (JAIC). The hybrid model follows the primary electron population using a Monte Carlo code that runs on a GPU, and computes the contribution of the secondaries using a two‐stream approximation.
