Evidence and Causes of an Unusual Super Plasma Bubble Occurrence During Weak Geomagnetic Conditions Over Europe

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.

Interplanetary magnetic fields, their fluctuations, and cosmic ray variations [PDF]

The cause of Forbush decreases is examined using neutron monitor data and measurements of the interplanetary magnetic field. It is found that for the period examined (Dec.

Solar Sector Structure

, 2015
The interplanetary magnetic field near has a characteristic "sector" structure that reflects its polarity relative to the solar direction. Typically we observe large-scale coherence in these directions, with two or four "away" or "towards" sectors per ...

Evolution of the interplanetary magnetic field [PDF]

, 1994
Remote observations of magnetic field topologies in the solar corona and in situ observations of the solar wind and interplanetary magnetic field (IMF) in interplanetary space are used to examine the temporal evolution of the spatial distribution of open and closed field regions emanating from the Sun.

The Relationship Between the Magnetometer Data Derived GIC Index and Measured GIC in High Voltage Transformers in Australia

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 ...

Forecasting SEP Atmospheric and Space Radiation by Coupling UMASEP and NAIRAS Models

Space Weather, Volume 24, Issue 1, January 2026.
Abstract The Nowcast of Aerospace Ionizing RAdiation System (NAIRAS) model predicts the radiation environment from the Earth's surface to free‐space. The model output provides dosimetric and particle flux quantities required to assess the hazardous radiation impacts to human health and adverse effects on vehicle electronic systems.
