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.

Energetic Proton Dropouts During the Juno Flyby of Europa Strongly Depend on Magnetic Field Perturbations

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract During Juno's only flyby of Europa, the Jupiter Energetic Particle Detector Instrument (JEDI) measured complex dropouts in the energetic ion flux in Europa's wake. We investigate the causes of these dropouts, focusing specifically on energetic protons of ∼100 ${\sim} 100$ keV and ∼1 ${\sim} 1$ MeV, using back‐tracking particle simulations, a ...

Ionospheric Density Variations Observed by the Radio Receiver Instrument on e‐POP/Swarm‐E

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract Ionospheric density variations can be inferred by studying the effects of electron density structures on transionospheric High Frequency (HF) radio wave propagation. The Radio Receiver Instrument (RRI) on the Enhanced Polar Outflow Probe (e‐POP)/Swarm‐E is used to detect HF radio waves during transionospheric experiments conducted between the ...

Correlation Patterns of Muon Flux With Vertical Atmospheric Profiles: Insights From Monte Carlo Simulations

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract The production, attenuation, and absorption of secondary cosmic rays (SCR) are influenced by atmospheric parameters such as air pressure and temperature. To reliably correlate SCR flux measurements with atmospheric ionization driven by energetic particle precipitation, these dependencies must be quantified.

Multi‐Platform Observations of the Radial Penetration of Substorm Injected Electrons and Subsequent Slot‐Filling Event

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract On 15 February 2018 a co‐rotating interaction region (CIR) from an equatorial coronal hole reached the Earth. The CIR initiated a moderate and slowly intensifying geomagnetic storm, which began with a large and strong substorm injection.

Omega Bands as a Source of Large dB/dt in the Dawn Sector

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract Omega band activity has the potential to cause geomagnetically induced currents as they can cause large values of dB/dt $\mathrm{d}B/\mathrm{d}t$. We have undertaken a multi‐instrument study of an omega event which occurred from 13 to 14 November 2012, during a period of southward IMF. Measurements from the European Incoherent SCATter (EISCAT)

APXS Derived Geochemistry of Shallow Water Lens Bodies Within the Mirador Formation, Gale Crater, Mars—Evidence for Intermittent Wet Periods and Implications for the Water Record

Journal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.
Abstract The Mount Sharp group in Gale crater is typically interpreted to record a progressive change (with increasing elevation) from wetter fluvio‐lacustrine environments to dry, eolian environments. This shift has been linked to orbital evidence for a global change in environmental and depositional conditions leading to an overall drying out of Mars.

Effects of Mineralogy and UV Radiation on the Detectability of Amino Acids Within the Martian Regolith: The Case for a Combined Chromatographical and Spectroscopical Approach

Journal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.
Abstract Amino acids are an extremely heterogeneous group of biomolecules essential for life on Earth. Their biosignatures are expected to be easily degraded on the Martian surface as the absence of a thick atmosphere and a magnetosphere leads to most of the solar radiation directly reaching its surface.

Modeling of Magnetic Local Time Asymmetry in Storm‐Time Low‐Latitude Geomagnetic Field Disturbances Due To Partial Ring Current

Space Weather, Volume 23, Issue 11, November 2025.
Abstract The intensity of storm‐time disturbance in the ground magnetic field varies significantly at different longitudes due to the magnetic local time (MLT) dependent contributions from different magnetospheric and ionospheric currents. Local geomagnetic field disturbances at low‐to‐mid latitudes often deviate considerably from the global depression

Ion Composition and Electron Pitch Angle Variations for Interchange Events in Jupiter's Inner Magnetosphere

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract The outward transport of plasma and magnetic fluxes in the gas giant magnetospheres is balanced with a return flow of flux tubes emptied through magnetic reconnection. Evidence of interchange motions between inward and outward moving flux tubes have long been reported around Jupiter and Saturn.
