Statistical Analysis of the Equatorward UV Auroral Emissions of the Jovian Southern Hemisphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract This study presents a comprehensive statistical analysis of Jupiter's southern UV auroral emissions, with a focus on the secondary oval and equatorward injection signatures. Utilizing Hubble Space Telescope (HST) data, the frequency, location, and intensity of these auroral features are systematically evaluated, considering their variation ...

Europa's Neutral Sodium Exosphere Is Quasi‐Stable Over Decades

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract Europa's sodium cloud is thought to be modified by its orbital longitude and by its plasma environment, which modulates with Jovian magnetic geometry. To explore and quantify sodium cloud variability, seven sets of Keck I/HIRES measurements are compared providing comprehensive coverage of orbital and magnetic geometry.

Coupled Thermosphere–Ionosphere–Plasmasphere Disturbances During the April 2023 Geomagnetic Storm: A Ground‐Based Multiparametric Study Across the American and European Sectors

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract The April 2023 geomagnetic storm significantly impacted the thermosphere‐ionosphere system, particularly over South America and midlatitude regions. This study analyzes ground‐based geomagnetic and ionospheric data, alongside Swarm satellite measurements, to investigate the physical mechanisms driven by intense solar wind energy input ...

Response of Thermospheric Nitric Oxide (NO) Cooling During Events of Strong Solar Wind Pressure

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract Nitric oxide (NO) infrared emissions are a notable indicator for varying thermospheric energy budget during geomagnetic storms while the Interplanetary Magnetic Field (IMF) is southward. In this study, we present the first investigation on the response of NO cooling emissions during northward IMF conditions.
