Exploring Enceladus's Interior Structure Using Electromagnetic Induction

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Electromagnetic (EM) sounding can constrain the electrical structure of Enceladus and, in turn, the salinity of its ocean and the porosity, fluid content, and thermal state of its hydrothermally active core. Here, we assess the feasibility of EM sounding at Enceladus using both global (orbiter) and local (lander) EM induction transfer ...

Ionospheric Effects on Maximum Usable Frequency for a Cross‐Auroral and a Polar Cap HF Radio Link

Radio Science, Volume 61, Issue 5, May 2026.
Abstract Maximum usable frequency (MUF) is an important indicator of the ability of the ionosphere to support over‐the‐horizon propagation of high frequency (HF) radio waves. MUF depends on the location of the transmitter and receiver, and the structure of ionospheric electron density.

The Extreme GIC Occurrence During 11 years of Observations in the North‐West of Russia

Space Weather, Volume 24, Issue 5, May 2026.
Abstract For the first time, events with extreme magnitudes of geomagnetically induced currents (GICs) in the power lines during the quasi‐solar cycle (2012–2022) at auroral and subauroral latitudes are analyzed. GIC recordings from auroral Vykhodnoy (Murmansk region) and subauroral Kondopoga (Karelia) sub‐stations together with data from near‐by ...

Extreme Value Analysis of Solar Green‐Line Corona During the Time Interval 1939–2025

Space Weather, Volume 24, Issue 5, May 2026.
Abstract Predicting the probability of extreme solar events is critical to understanding how to mitigate risks associated with space weather disasters, as their occurrence can pose a threat to life and infrastructure on Earth or in near‐Earth orbit. In the present study, extreme value theory is applied to the daily modified coronal index (MCI) for the ...

GIC‐Related Observations During the May 2024 Geomagnetic Storm in the United States

Space Weather, Volume 24, Issue 5, May 2026.
Abstract The May 2024 geomagnetic storm was one of the most severe in the past 20 years. Understanding how large geomagnetic disturbances (GMDs) impact geomagnetically induced currents (GICs) within electrical power grid networks is key to ensuring their resilience.

Ionospheric Amplitude Scintillation Evolution Characterizing Using High Resolution S4 Index in the Crests of the EIA Regions During Solar Maximum Periods

Space Weather, Volume 24, Issue 5, May 2026.
Abstract Ionospheric scintillation in the Equatorial Ionization Anomaly (EIA) region significantly impacts the performance of Global Navigation Satellite System (GNSS). While scintillation characteristics have been widely studied globally, the evolution of scintillation events remains underexplored.

A High‐Efficiency Multivariable TEC‐SOFTS Model for Ionospheric TEC Prediction: Validation Over China Area During Low and High Solar Activity Periods

Space Weather, Volume 24, Issue 5, May 2026.
Abstract The ionospheric Total Electron Content (TEC) is a key parameter for characterizing the ionospheric properties. In this study, an efficient multivariable time series prediction model, TEC‐Series Core Fusion and efficient multivariable time series (TEC‐SOFTS), was constructed by combining multiple geomagnetic and solar activity indices ...

Investigating the Impact of Rocket Exhaust on Ionospheric Disturbances

Space Weather, Volume 24, Issue 5, May 2026.
Abstract The study of chemical releases into the ionosphere is crucial for understanding ionospheric dynamics and managing space environmental effects. In this work, we investigate the impact of rocket exhaust emissions, particularly CO2 and H2O, on electron density in the ionosphere.
