High‐Latitude Electrodynamics and Thermospheric Density Variations During the 2024 Gannon Storm
Space Weather, Volume 24, Issue 2, February 2026.Abstract This study investigates high‐latitude electrodynamics and thermospheric density variations during the 2024 Gannon's storm. First, the auroral precipitation module of Auroral Spectra and High‐Latitude Electric field variabilitY, ASHLEY‐A, is improved to more accurately capture the location of auroral precipitation observed during this ...

The Geomagnetic Storm on 10–12 May 2024 and Its Effect on the Swedish Power Grid
Space Weather, Volume 24, Issue 2, February 2026.Abstract On 10–12 May 2024, at least five interplanetary coronal mass ejections (ICMEs) arrived at Earth and caused the strongest geomagnetic storm in over 20 years. During this geomagnetic storm, a disturbance occurred in a transformer in southern Sweden, causing a drop in power supply in the power line connecting Sweden and Poland.

Space Weather, Volume 24, Issue 2, February 2026.Abstract On 10 May 2024, a severe G5 geomagnetic storm—the most intense of solar cycle 25—significantly disturbed the global ionosphere. This study presents a comprehensive analysis using multi‐instrument observations, including ground‐based measurements from BDS‐GEO total electron content (TEC), digital ionosondes, and magnetometers; model outputs ...

Sampling the volcanic plumes at Io: Impact speeds and shock conditions
Meteoritics &Planetary Science, Volume 61, Issue 2, Page 241-271, February 2026.Abstract The desire to sample material from the interior of Io, by flying through its volcanic plumes, requires consideration of the flyby speed and the types of sample collection techniques that can be utilized. Low speed collection (1–2.5 km s−1) would require an orbit around Io itself, which is unlikely due to the accumulated radiation dose that ...

Low Frequency Oscillation Observed in the Ionosphere Around the Substorm Onsets
Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract Three substorm events in which Defense Meteorological Satellite Program (DMSP) spacecraft are geomagnetically co‐located with substorm onset locations in IMAGE far ultraviolet auroral images are analyzed. A Hilbert‐Huang Transform is used to decompose the DMSP B⊥ ${B}_{\perp }$ in the ionosphere to its intrinsic mode functions. A dominant mode

Multipoint Observations of a SLAMS Evolution and Its Merger With Whistler Waves
Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract We report multipoint observations of a merger between a Short Large‐Amplitude Magnetic Structure (SLAMS) and 1‐Hz whistler wave packets upstream of Earth's quasi‐parallel bow shock. Using high‐resolution data from the Magnetospheric Multiscale (MMS) mission in a string‐of‐pearls configuration, we track the SLAMS as it evolves, exhibiting ...

The Energy Cascade Rate in Supersonic Magnetohydrodynamic Turbulence
The Astrophysical JournalThree-dimensional direct numerical simulations are implemented to investigate the energy cascade rate in compressible isothermal magnetohydrodynamic turbulence. Utilizing an exact law derived from the Kármán–Howarth equation, we examine the contributions

Plasma Conditions Govern the Reversible Transition Between STEVE and Picket Fence Emissions
Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract On 6 May 2018, a remarkable subauroral optical event exhibiting three phases of evolution (Strong Thermal Emission Velocity Enhancement [STEVE] → Picket Fence → STEVE) and co‐occurrence with a stable auroral red arc was observed over Alberta, Canada.

BepiColombo at Mercury: Three Flybys, Three Magnetospheres
Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract We examine the first three BepiColombo Mercury flybys Using data from the Miniature Ion Precipitation Analyzer (MIPA), an ion mass analyzer in the Search for Exospheric Refilling and Natural Abundances package on the Mercury Planetary Orbiter designed to study magnetospheric dynamics.
