Propagation of Interplanetary Shocks in the Heliosphere

, 2023
Interplanetary shocks are one of the crucial dynamic processes in the Heliosphere. They accelerate particles into a high energy, generate plasma waves, and could potentially trigger geomagnetic storms in the terrestrial magnetosphere disturbing significantly our technological infrastructures. In this study, two IP shock events are selected to study the

Extension, Improvements and Perspectives of the Cluster GRMB Data Set

Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract The purpose of the Geospace Region and Magnetospheric Boundary identification (GRMB) data set is to provide information on the regions crossed by each of the 4 Cluster spacecraft during the entire mission. The data set includes 15 labels, 11 for regions and transition regions (TR): plasmasphere, plasmapause TR, plasmasheet, plasmasheet TR ...

The Influence of Topography and Crustal Magnetic Anomalies on the Distribution of Water Ice in the Lunar South Pole Region

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract Lunar magnetic anomalies are abundant near the south pole, where several moderate‐strength anomalies spatially overlap permanently shadowed regions (PSRs). This environment provides a unique setting to assess how crustal magnetic fields and topography regulate plasma–surface interactions and, in turn, the stability and distribution of surface ...

Computations on the interaction of an interplanetary shock with the Earth's magnetosphere

Astrophysics and Space Science, 1977
We present the results of a one-dimensional computer simulation of the interaction between interplanetary shocks and the Earth's magnetosphere. The position of the bowshock as a function of solar wind velocity and interplanetary field direction is studied.

Simulation of GIC in the North Island of Aotearoa New Zealand Based on Magnetotelluric Measurements

Space Weather, Volume 24, Issue 7, July 2026.
Abstract New magnetotelluric (MT) data, combined with older MT data are used to simulate geomagnetically induced currents (GIC) in the power network of the North Island of Aotearoa New Zealand for two geomagnetic storms. For the May 2024 G5 Gannon Storm, simulations use magnetic field data from two separate locations—the Intermagnet geomagnetic ...

A Model for Recommending Historical Similar Events in Forecasting CME Geoeffectiveness

Space Weather, Volume 24, Issue 7, July 2026.
Abstract Coronal mass ejections (CMEs) are among the key solar eruptive activities, triggering space weather disturbances. Thus, forecasting their geoeffectiveness has become a research focus. This study constructs a model to recommend similar events for forecasting the geoeffectiveness of CMEs.

Predicting the Arrival Time of an Interplanetary Shock Based on DSRT Spectrum Observations for the Corresponding Type II Radio Burst and a Blast Wave Theory

The Astrophysical Journal
Since fast head-on coronal mass ejections and their associated shocks represent potential hazards to the space environment of the Earth and even other planets, forecasting the arrival time of the corresponding interplanetary shock is a priority in space ...

Large, Long‐Lasting Mid‐Latitude Geomagnetically Induced Currents During a Moderate Geomagnetic Storm

Space Weather, Volume 24, Issue 7, July 2026.
Abstract Geomagnetically Induced Currents (GICs) are a key space weather hazard to ground‐based infrastructure, and can cause mis‐operation or even equipment failure. The solar wind interacts with the Earth's geomagnetic field, causing the magnetic field at ground level to vary with time.
