Simultaneous TRACERS and THEMIS Observations of Reversed Cusp Ion Dispersions and Dual‐Lobe Reconnection

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract We present observations from two consecutive TRACERS‐2 orbits through the northern low‐altitude cusp. During the first crossing, TRACERS‐2 observed reversed cusp ion dispersion and sunward convection, consistent with magnetopause reconnection tailward of the cusp during this northward IMF interval.

Emergent Chaos‐Like Dynamics of Spin–Orbit‐Torque‐Driven Magnetic Transitions

Small, Volume 22, Issue 37, 2 July 2026.
By combining anisotropy‐engineered nanometer‐scale nucleation sites with time‐resolved x‐ray holography and micromagnetic modeling, magnetization dynamics are directly imaged, revealing chaos‐like fluctuations and skyrmion shedding and highlighting the intrinsic complexity of spin‐orbit torque driven systems.

Global Observational Comparison of Large‐Scale Traveling Atmospheric and Ionospheric Disturbances During the May 2024 Geomagnetic Storm

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract During the geomagnetic storm on 10 May 2024, neutral density measurements from 14 Tianmu, Swarm, and GRACE‐FO satellites at ∼510 km altitude, combined with total electron content (TEC) observations, enabled the first global observational comparison of large‐scale traveling atmospheric and ionospheric disturbances (LSTADs/TIDs) via snapshots ...

The Drag of Ionosphere Plasma Drifts on Thermospheric Zonal Winds During the 10–12 May 2024 Superstorm

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The observations from GRACE‐FO and DMSP satellites are utilized to analyze the ion‐neutral interaction near dusk during the 10–12 May 2024 super‐storm. The horizontal plasma convection dragged the anti‐sunward wind in the polar cap and sunward winds around the auroral and subauroral regions during whole storm times.
