AKR Observations From All Local Times Indicate Substorm Activity

Journal of Geophysical Research: Space Physics, Volume 130, Issue 9, September 2025.
Abstract Auroral Kilometric Radiation (AKR) is known to present emission at lower frequencies near substorm onset, corresponding to activation of higher altitude sources along auroral magnetic field lines and acting as a proxy of the vertical distribution of acceleration processes during these events.

Stability of the Earth's Dayside Magnetosheath: Effects of Upstream Solar Wind Structures and Downstream Jets

Journal of Geophysical Research: Space Physics, Volume 130, Issue 9, September 2025.
Abstract The constant stream of plasma from the Sun, the solar wind, forms a bow shock as it interacts with Earth's magnetic field. The plasma properties change drastically as it crosses the shock and enter the downstream magnetosheath. This extended region hosts various kinetic ion plasma instabilities, such as mirror modes, ion cyclotron waves, and ...

Global Effects of Magnetic Anomalies on the Near‐Surface Lunar Plasma Environment

Journal of Geophysical Research: Space Physics, Volume 130, Issue 9, September 2025.
Abstract The interaction between lunar magnetic anomalies and the solar wind plasma creates unique structures known as “lunar mini‐magnetospheres,” which reflect and partially shield the lunar surface from impinging solar wind protons. Using data from the Sub‐KeV Atom Reflecting Analyzer onboard Chandrayaan‐1, we produce new surface maps of energetic ...

Injections of Multi‐MeV Electrons in the Magnetosphere of Jupiter

Journal of Geophysical Research: Space Physics, Volume 130, Issue 9, September 2025.
Abstract Energetic particle injections provide a means for fast inward radial transport and adiabatic acceleration of electrons in the magnetosphere of Jupiter. Furthermore, enhanced whistler‐mode wave activity during injections can further accelerate electrons to MeV energy.

Impact of Gravity Waves From Tropospheric and Non‐Tropospheric Sources on the Middle and Upper Atmosphere and Comparison With ICON/MIGHTI Winds

Journal of Geophysical Research: Space Physics, Volume 130, Issue 9, September 2025.
Abstract We study the dynamical and thermal roles of internal gravity waves generated in the troposphere and above using the Coupled Middle Atmosphere Thermosphere‐2 General Circulation Model. This model incorporates the whole atmosphere nonlinear spectral gravity wave parameterization and its extension to include non‐tropospheric sources. We conducted

Fermi Acceleration of Electrons at Earth's Bow Shock Due To Current Sheet Interaction

Journal of Geophysical Research: Space Physics, Volume 130, Issue 9, September 2025.
Abstract We use the Magnetospheric Multiscale (MMS) mission to present a case study of electron acceleration at Earth's bow shock due to an interaction with a solar wind magnetic depression. The magnetic depression is identified as a reconnecting current sheet and is observed both at the bow shock, using MMS, and upstream of the shock at the Lagrange ...
