Assessment of Space Weather Impacts on New Zealand Power Transformers Using Dissolved Gas Analysis
Space WeatherSpace weather can have major impacts on electrical infrastructure. Multiple instances of transformer damage have been attributed to geomagnetic storms in recent decades, for example, the Hydro Quebec incident of 1989 and the November 2001 storm in New ...

Space Weather, Volume 24, Issue 1, January 2026.Abstract Using data from a cluster of ground‐based global navigation satellite system, we observed spatially extended enhanced ROTI over the European longitudes during a weak geomagnetic storm (Dst ≈ ${\approx} $ −50 nT) on 4 November 2023. The enhanced ROTI is extended over an extensive geographical latitudinal range of 46°N.

Antarctic Record, 1980 This is an attempt to identify the causes of geomagnetic storms which occurred during a year and a half from January 1977 to June 1978. The assignment of geomagnetic storm causation to appropriate coronal holes or solar flares has been made by ...

Solar sources of geomagnetic storms
Eos, Transactions American Geophysical Union, 1992 Because geomagnetic storms can have important effects on communications and electrical power distribution, an ability to predict these storms has considerable value. We have recently come to understand that coronal mass ejections (CMEs) cause most large geomagnetic storms during the most active part of the solar cycle [Gosling et al., 1991].

Space Weather, Volume 24, Issue 1, January 2026.Abstract Geomagnetically induced currents (GICs) are telluric currents driven by space weather that can adversely impact high voltage transformers in electricity supply networks. It is often difficult to obtain transformer GIC data so ground based magnetometer data may be used to estimate the transformer GIC via complex modeling of both network and ...

Driving Dynamical Inner‐Heliosphere Models With In Situ Solar Wind Observations
Space Weather, Volume 24, Issue 1, January 2026.Abstract Accurately reconstructing the solar wind throughout the inner heliosphere is essential for understanding solar–terrestrial interactions and improving space‐weather forecasts. Conventional reconstruction methods rely on photospheric magnetic field observations and coronal models to estimate solar wind conditions near the Sun, typically at 0.1 ...

Space Weather, Volume 24, Issue 1, January 2026.Abstract Understanding and forecasting extreme radiation belt electron fluxes has been a major goal in space weather since their discovery in 1958. In this study, by combining electron flux data from multiple satellite missions in different orbits, including Van Allen Probes, Electron Losses and Fields Investigation, and Colorado Inner Radiation Belt ...
