Abstract This paper presents a global statistical investigation into the topside ionosphere electron density response to X‐class solar flares during geomagnetically quiet conditions (Kp ≤ $\mathit{\le }$ 2) using Swarm satellites (462–511 km) data from 2014 to 2024.

First Report of Rising‐Tone EMIC Waves Driven by the Magnetosheath High‐Speed Jet
Abstract Magnetosheath high‐speed jets (HSJs) are pervasive transient structures with enhanced dynamic pressure in the terrestrial magnetosheath and can exert notable local impacts on the magnetopause. Although various geoeffects have been reported to be associated with HSJs, whether HSJs can drive the generation of electromagnetic ion cyclotron (EMIC)

Controlling of the F Region Plasma Structures by the E Region Conductance in the Auroral Ionosphere
Abstract At high latitudes, the E and F regions of the ionosphere are strongly coupled through nearly vertical magnetic field lines. To simultaneously and directly relate the E and F regions' plasma structures, we ran a coordinated conjunction campaign between Swarm satellites and Incoherent Scatter Radar in Tromsø, Norway, during a moderate ...

Abstract Low‐velocity layers (LVLs) above the 410‐km discontinuity are commonly attributed to partial melt generated by dehydration melting when hydrous mantle transition‐zone material rises into the upper mantle, where water solubility in nominally anhydrous minerals decreases.

Enhancement of Dayside Westward Electrojet: Triggering Conditions and Current Closures
Abstract Geomagnetic substorms are a major path for energy storage and release in the magnetosphere, which typically occur in the midnight sector with a strong enhancement of westward electrojets. However, by analyzing 37,940 events from a substorm list, about 3% of events unexpectedly initiated in the noon sector.

Residual Magnetization Accumulation Enables Rapid Pre‐Polarized Surface NMR Groundwater Detection
Abstract Surface nuclear magnetic resonance (SNMR) directly detects subsurface water, but its field application is constrained by the trade‐off between signal enhancement and survey throughput. Conventional pre‐polarization strengthens SNMR signals but requires long polarization pulses that markedly prolong acquisition. Here we show that repeated short

Ultra‐Low‐L Sub‐MeV Electron Microbursts During the May 2024 Super Storm
Abstract During the May 2024 super storm, we identified sub‐second microburst‐type relativistic electron precipitation events at McIlwain's L∼2 $L\sim 2$ in low‐Earth orbit using the Gamma‐ray Burst Monitor (CGBM) onboard the CALorimetric Electron Telescope on the International Space Station.
