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

The Extreme GIC Occurrence During 11 years of Observations in the North‐West of Russia

Space Weather, Volume 24, Issue 5, May 2026.
Abstract For the first time, events with extreme magnitudes of geomagnetically induced currents (GICs) in the power lines during the quasi‐solar cycle (2012–2022) at auroral and subauroral latitudes are analyzed. GIC recordings from auroral Vykhodnoy (Murmansk region) and subauroral Kondopoga (Karelia) sub‐stations together with data from near‐by ...

Simulation of January 1-7, 1978 events [PDF]

The solar wind disturbances of January 1 to 7, 1978 are reconstructed by a modeling method. First, the interplanetary magnetic field (IMF) background pattern, including a corotating shock, is reproduced using the Stanford source surface map.

Unique Observations of a Geomagnetic SI^+ -- SI^- Pair: Solar Sources and Associated Solar Wind Fluctuations

, 2010
The paper describes the occurrence of a pair of oppositely directed sudden impulses (SI), in the geomagnetic field ($\Delta$X), at ground stations, called SI${^{+}}$ -- SI${^{-}}$ pairs, that occurred between 1835 UT and 2300 UT on 23 April 1998. The SI${

How Does the Definition of a Geomagnetic Storm Affect the Contents of the Resulting Storm List?

Space Weather, Volume 24, Issue 5, May 2026.
Abstract A geomagnetic storm is a significant and prolonged disturbance of the Earth's magnetic field caused by an enhancement of the ring current. Storms are typically identified using magnetic field measurements from multiple ground‐based magnetometers, and the corresponding dates and times of multiple storms can be collated to form a storm list ...

Search for a simultaneous signal from small transient events in the Pierre Auger Observatory and the Tupi muon telescopes

, 2011
We present results of a search for a possible signal from small scale solar transient events (such as flares and interplanetary shocks) as well as possible counterparts to Gamma-Ray Burst (GRB) observed simultaneously by the Tupi muon telescope Niteroi ...

Leveraging Legacy Broadband Magnetotelluric Data for Geoelectric Field Hazard Assessment in Southern Italy

Space Weather, Volume 24, Issue 5, May 2026.
Abstract Geomagnetically induced currents (GICs) are a significant space weather hazard. Their accurate assessment requires estimating the geoelectric field, which depends on the Earth's subsurface electrical conductivity. While long‐period magnetotelluric (MT) surveys are ideal, archives of legacy broadband MT data, originally acquired for geological ...

Predicting CME Arrivals From L5 Heliospheric Imagers: The Impact of HI Track Length

Space Weather, Volume 24, Issue 5, May 2026.
Abstract The Solar TErrestrial RElations Observatory (STEREO) mission has laid a foundation for advancing real‐time space weather forecasting by enabling the evaluation of heliospheric imager (HI) data for predicting coronal mass ejection (CME) arrivals at Earth.
