Space Weather Effects From Moderate to Severe Geomagnetic Storms in October 2024 Over the Latin American Sector

Space Weather, Volume 24, Issue 6, June 2026.
Abstract This study presents a detailed case study of the ionospheric impacts of moderate (G2) and severe (G4) geomagnetic storms over the Latin American sector, with particular emphasis on the formation and suppression of equatorial plasma bubbles (EPBs).

TEC Prediction Using Cross‐Attention Spatiotemporal Feature Weighted BiConvLSTM and Improved Pre‐Earthquake Anomaly Detection

Space Weather, Volume 24, Issue 6, June 2026.
Abstract To address the complex spatiotemporal characteristics of ionospheric total electron content (TEC), a bidirectional convolutional long short‐term memory network with a dynamic cross‐attention mechanism for spatiotemporal feature weighting (CASF‐BiConvLSTM) is proposed and further combined with the sliding interquartile range (SIQR) method ...

Validating SCUBAS Predictions of Geomagnetically Induced Voltage in Submarine Cables Using Legacy Superstorm Observations

Space Weather, Volume 24, Issue 6, June 2026.
Abstract Modern submarine communication cables, though fiber‐optic in nature, remain vulnerable to space weather hazards due to their internal conductive cables used for powering repeaters. During geomagnetic storms, variations in the geomagnetic field induce geoelectric fields that drive geomagnetically induced voltages along these cables.

Terrestrial Space Weather Protection Through Human‐Produced Mass‐Loading

Space Weather, Volume 24, Issue 6, June 2026.
Abstract While humans become more reliant on Earth's space environment, the potential for significant harm from severe space weather continues to grow. As structures from the sun reach Earth's magnetosphere and space environment, they deposit energy that fuels geomagnetic storms.

High‐Latitude GPS Position Error During Substorms

Space Weather, Volume 24, Issue 6, June 2026.
Abstract Substorms produce rapid fluctuations in Global Navigation Satellite System (GNSS) signals, leading to degraded positioning performance at high latitudes. This study investigates the correlation of auroral structures on Global Positioning System (GPS) Precise Point Positioning (PPP) error during three substorm events with different strengths ...

ST‐TFFM‐Observer: A Global Ionospheric TEC Prediction Model Based on Dynamic System Theory With Enhanced Time‐Frequency Dependence Modeling

Space Weather, Volume 24, Issue 6, June 2026.
Abstract ST‐Observer is a novel proposed spatiotemporal prediction model based on dynamic system theory, which has been proven to be superior to existing models in multiple spatiotemporal prediction tasks. However, its structural design results in weak time dependent modeling capabilities and a lack of frequency dependent modeling capabilities.

Ionospheric Characterization Over Iran Using Multi‐Frequency IMB HF Transmitters and Global WSPRNET Reception During the 12 November 2025 Geomagnetic Storm

Space Weather, Volume 24, Issue 6, June 2026.
Abstract The Ionospheric Monitoring Beacon network in Iran provides continuous, multi‐frequency high‐frequency (HF) transmissions using WSPRNET modulation, enabling global reception and near–real‐time monitoring of ionospheric propagation conditions.
