Solar Wind and Geomagnetic Conditions That Lead to the Largest Relativistic Electron Fluxes in GPS Orbit

Space Weather, Volume 23, Issue 11, November 2025.
Abstract Relativistic electrons are an important space weather hazard, being a major source of radiation damage to satellites and posing a risk to humans in space. We use approximately 20 years of data from the US Global Positioning System (GPS) satellite NS41 to determine the characteristics of the geomagnetic storms that lead to the largest ...

Modeling and Risk Assessment of Geomagnetically Induced Currents During Geomagnetic Storm in the 500 kV Power Grid of Guangxi, China

Space Weather, Volume 23, Issue 11, November 2025.
Abstract Geomagnetic storms can induce geomagnetically induced currents (GIC) in power systems, posing threats to grid security. In this study, a GIC calculation model for the 500 kV power grid in Guangxi, China, is developed based on one‐dimensional (1D) and various three‐dimensional (3D) magnetotelluric (MT) impedance data.

New Results on the Onset of a Coronal Mass Ejection from 5303 Å Emission Line Observations with VELC/ADITYA-L1

The Astrophysical Journal Letters
We report on the onset of a coronal mass ejection (CME) using spectroscopic observations in the 5303 Å coronal emission line with the Visible Emission Line Coronagraph (VELC) onboard ADITYA-L1, the recently launched first Indian space solar mission.

Impacts of Space Weather‐Induced Satellite Navigation Errors on UAV Collision Risk: An Estimation for Parallel and Crossing Routes

Space Weather, Volume 23, Issue 11, November 2025.
Abstract Satellite navigation systems are vulnerable to space weather disturbances, which can degrade positioning accuracy and potentially increase the collision risk of unmanned aerial vehicles (UAVs). This study investigates the influence of navigation errors caused by ionospheric scintillation on UAV encounter scenarios. Two route configurations are
