Using Solar Wind Data Assimilation Results to Drive Dynamic Solar Wind Models

Space Weather, Volume 23, Issue 9, September 2025.
Abstract A coupled modeling framework is often used to forecast the near‐Earth solar wind conditions. This consists of a coronal model for close to the Sun and a heliospheric model for propagating the solar wind out to Earth. The coronal model is initialized using photospheric magnetic field observations and beyond this, there are no further ...

Energization of Separatrix Electrons by Plasma Double Layers During Asymmetric Magnetic Reconnection

Geophysical Research Letters, Volume 52, Issue 16, 28 August 2025.
Abstract Particle acceleration in magnetic reconnection is a critical area that demands investigation for a better understanding of energization processes in space plasma. NASA's Magnetospheric Multiscale Mission detected multiple separatrix crossings during the asymmetric magnetic reconnection at Earth's subsolar magnetopause.

Prolonged Intervals of Relativistic Electron Storm‐Time Flux Enhancements in the Magnetotail at Lunar Distance

Geophysical Research Letters, Volume 52, Issue 16, 28 August 2025.
Abstract We report on prolonged enhancements of electron fluxes at energies at or above 500 keV, observed in the magnetotail by the lunar‐orbiting Acceleration, Reconnection, Turbulence, and Electrodynamics of Moon's Interaction with the Sun (ARTEMIS) during the recovery phase of a magnetic storm with minimum Dst ${D}_{st}$ ≈ ${\approx} $ −200 nT ...

Statistical Study on L‐O Mode Saturn Kilometric Radiation

Geophysical Research Letters, Volume 52, Issue 15, 16 August 2025.
Abstract Based on the 13 years‐long observation of Saturn kilometric radiation (SKR) by the Cassini/Radio and Plasma Wave Science instrument, this study derives statistics for left‐hand (L‐O) mode SKR emissions. These emissions span a frequency range from below 10 kHz to approximately 1,000 kHz, with spectral flux densities ranging between 10−24 and 10−

Strong Westward Current Pulse at Auroral Latitudes Extending to Dawn‐Side Low‐Latitudes Due To Enhanced Density Within Kelvin‐Helmholtz Wave Vortex in Solar Wind

Geophysical Research Letters, Volume 52, Issue 15, 16 August 2025.
Abstract A series of coronal mass ejections (CMEs) from the Sun, interacted with one another and formed a complex interplanetary‐CME (ICME) that impinged Earth's magnetosphere on 10 May 2024 and caused the strongest geomagnetic storm of the past two decades.

PAOPS (Prenoon Auroral Oval Poleward Shift): A Novel Prenoon‐Postnoon Auroral Asymmetry Phenomenon Revealed by Simultaneous Interhemispheric Observations

Geophysical Research Letters, Volume 52, Issue 15, 16 August 2025.
Abstract Previous studies indicate that specific polar cap auroral forms frequently occur in the postnoon in summer due to the influence of the interplanetary magnetic field (IMF) By component. However, regardless of the season and IMF conditions, similar auroral forms rarely occur in the prenoon. The reason for this asymmetry remains a mystery.

Comprehensive Analysis of Bias in TEMPO NO2 Column Densities Through Pandora Observations

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 15, 16 August 2025.
Abstract Tropospheric Emissions: Monitoring of Pollution (TEMPO) is the first geostationary satellite instrument to monitor air pollutants across North America. This study uses Pandora observations to analyze the bias in TEMPO Level‐3 total column density of NO2 (TOTNO2) from August 2023 to December 2024.
