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.

Acceleration and Release of Solar Energetic Particles Associated with a Coronal Shock on 2021 September 28 Observed by Four Spacecraft

The Astrophysical Journal
The main driver of the acceleration of solar energetic particles (SEPs) is believed to be shocks driven by coronal mass ejections. Extreme-ultraviolet (EUV) waves are thought to be the propagating footprint of the shock on the solar surface.

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,

The Role of Magnetic Skeleton in Solar Flare Filaments Activity

The Astrophysical Journal
We report an M9.3 flare and filaments activities from NOAA Active Region 11261 that are strongly modulated by the 3D magnetic skeleton. Magnetic field extrapolation from the vector magnetic field suggests complex magnetic connectivity and the existence ...

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 ...

Mercury's Altered Magnetosphere During a Sub‐Alfvénic ICME Event: MESSENGER Observations and Inferred Asymmetric Alfvén Wing Formation From Global MHD Simulations

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract We present observations of a rare configuration of Mercury's magnetosphere in response to sub‐Alfvénic upstream conditions, driven by an interplanetary coronal mass ejection (ICME) that impacted the planet on 1 May 2013. Using data from the Mercury Surface, Space Environment, Geochemistry, and Ranging (MESSENGER) spacecraft, supported by a ...
