Statistical Analysis of Multiple Bow Shock Crossings at Mars

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract We conduct a statistical analysis of multiple bow shock (BS) crossings at Mars. Data from the magnetometer (MAG) and Solar Wind Ion Analyzer (SWIA) onboard the Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft from its first 2 years in orbit is used to identify flapping events.

Magnetopause Location and Solar Wind Turbulence Level During FDs and Their Impacts on the Global Electric Circuit

Space Weather
During Forbush decreases (FDs), the fluxes of high‐energy galactic cosmic rays (GCRs) are suppressed. As a consequence, the ionization profile of the atmosphere is affected and the global electric circuit system is perturbed.

Properties of Ion Upflows in the Low‐Altitude Polar Ionosphere During CIR‐ and CME‐ Driven Magnetic Storms Based on Long‐Term EISCAT Observations

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract We have investigated the effects of Corotating Interaction Region‐ (CIR‐) and Coronal Mass Ejection‐ (CME‐) driven magnetic storms on the characteristics and mechanisms of ion upflow in the low‐altitude ionosphere (250–350 km). Our analysis was based on observations from the European Incoherent Scatter (EISCAT) radars at Tromsø (ILAT = ∼66 ...

The Performance of DIXSG on Characterizing Global and Regional Ionospheric Disturbances Utilizing Geodetic Receiver Network‐A Case Study

Space Weather, Volume 23, Issue 10, October 2025.
Abstract As the 25th solar cycle enters a highly active phase, the resulting ionospheric irregularities induce disturbances in signals of Global Navigation Satellite System (GNSS), significantly disrupting its global stable positioning, navigation, and timing services.

Correlation Between Radiation Enhancements at Aviation Altitudes and Energetic Precipitating Electrons

Space Weather, Volume 23, Issue 10, October 2025.
Abstract The campaign of Automated Radiation Measurements for Aerospace Safety (ARMAS) has revealed that relativistic electron precipitation (REP) from the radiation belts can significantly enhance the radiation environment at aviation altitudes, in addition to the well‐known sources of galactic cosmic rays and solar energetic particles. Recent studies

Characteristics of Large‐Scale Traveling Ionospheric Disturbances During the 10 May 2024 Geomagnetic Storm

Space Weather, Volume 23, Issue 10, October 2025.
Abstract Based on the total electron content (TEC) observation in the Asian‐Australian and American sectors, this paper investigates the characteristics and hemispheric asymmetry of large‐scale traveling ionospheric disturbances (LSTIDs) during the 10 May 2024 superstorm. We found that the amplitudes and meridional phase velocities of LSTIDs in the two
