A Comparison of Modeled and Observed Dayside Bow Shock Locations in 8 Years of MMS Data

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract The interplay between Earth's magnetic field and the solar wind provides a natural laboratory to study the physics of shock waves in collisionless plasmas. 3D parameterized shape models of Earth's bow shock boundary quantify how this interaction depends on upstream solar wind parameters.

Disparities in Magnetic Cloud Observations between Two Spacecraft Having Small Radial and Angular Separations near 1 au

The Astrophysical Journal
Studies for inferring the global characteristics of coronal mass ejections (CMEs) from multipoint local in situ observations have been undertaken previously, but limited studies have utilized measurements from multiple spacecraft with sufficiently small ...

Turbulence development behind the bow shock during disturbed and undisturbed solar wind

Solar-Terrestrial Physics
Magnetosheath is a transition layer between the solar wind and the magnetosphere and may contribute to the geoeffectiveness of various large-scale interplanetary phenomena.

Inner Magnetospheric and Geomagnetic Responses to Solar Wind Driving During Omega Band Events

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract Omega bands are mesoscale auroral structures that appear as quasi‐periodic eastward drifting protrusions of the poleward edge of the diffuse aurora. Cribb et al. (2024), https://doi.org/10.1029/2024gl109756 demonstrated that the appearance of omega bands is associated with solar wind driving consistent with stream interaction regions. However,

Evidence linking coronal mass ejections with interplanetary magnetic clouds [PDF]

Using proxy data for the occurrence of those mass ejections from the solar corona which are directed earthward, we investigate the association between the post-1970 interplanetary magnetic clouds of Klein and Burlaga and coronal mass ejections.

Power Density Dissipated by Field‐Aligned Currents in the Topside Ionosphere Derived From Swarm‐A Observations

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract Magnetosphere‐ionosphere (MI) coupling is mainly achieved by field‐aligned currents (FACs) that inject energy and momentum into the high‐latitude ionosphere. A fraction of this energy is locally dissipated and converted into kinetic energy of the ionospheric plasma.

Midnight Simultaneous Observations of Spread‐F and Multiple F‐Layer Stratifications During the 11–12 May 2024 Geomagnetic Superstorm

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract A geomagnetic superstorm occurred from May 10 to 12, 2024, producing significant spatial and temporal disturbances in the ionosphere. Ground‐based ionosonde and GPS‐TEC data enabled the identification, analysis, and possible interpretation of a unique event: the simultaneous occurrence of Spread‐F and multiple F‐layer stratifications during ...

Constraining the Mass Loss and the Kinetic Energy of Stellar Coronal Mass Ejections with Solar Far-ultraviolet Flares

The Astrophysical Journal
Stellar eruptive events, such as flares and coronal mass ejections (CMEs), can affect planetary habitability by disturbing the stability of their atmospheres.
