Energetics of Shock-triggered Supersubstorms (SML < −2500 nT)
The Astrophysical Journal, 2023 The solar wind energy input and dissipation in the magnetospheric–ionospheric systems of 17 supersubstorms (SSSs: SML < −2500 nT) triggered by interplanetary shocks during solar cycles 23 and 24 are studied in detail. The SSS events had durations ranging

The May 2024 Storm: The Cusps and Dayside Magnetopause in Simulated Soft X‐Rays
Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract The coronal mass ejection (CME) arriving at Earth on 10 May 2024 caused the most intense geomagnetic storm in the last two decades, resulting in highly unusual cusp and magnetopause dynamics. We simulate soft X‐Ray emission due to solar wind charge exchange with exospheric neutrals to image the global dayside dynamics, focusing on the impact ...

Preliminary investigation of interplanetary shock structure: Quasi-parallel shocks [PDF]
, 1974 Pioneer 9's magnetic field and plasma data were studied to develop arguments for or against the observation of oblique interplanetary shocks. Structural classifications are defined, and the justification for seeking these classifications in the solar ...

Geoeffectiveness of interplanetary shocks controlled by impact angles: A review [PDF]
, 2018 The high variability of the Sun’s magnetic field is responsible for the generation of perturbations that propagate throughout the heliosphere. Such disturbances often drive interplanetary shocks in front of their leading regions.

Flat Spectra of Energetic Particles in Interplanetary Shock Precursors
The Astrophysical JournalThe observed energy spectra of accelerated particles at interplanetary shocks often do not match the diffusive shock acceleration (DSA) theory predictions. In some cases, the particle flux forms a plateau over a wide range of energies, extending upstream

Radio Sounding Determination of Two‐Dimensional Plasma Structure Velocity
Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract The Mars spacecraft Tianwen‐1 transmitted radio signals to Earth for its orbit determination. The frequencies of the radio signals exhibited sharp variations when an ICME passed through the Mars‐Earth signal path on 18 June 2021. These sharp variations were observed at different ground stations at different times. This was most probably caused

The θBn problem: Determination of local magnetic parameters of interplanetary shocks from in situ IMF data [PDF]
Geofísica Internacional, 2001 The angle θBn is the angle between the upstream magnetic field and the shock normal direction and is important for many phenomena in interplanetary physics.

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

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract Recent works suggest there are periods when the Sun encountered massive interstellar cold clouds which compressed the heliosphere to within Earth's orbit, exposing Earth to interstellar galactic cosmic rays and energetic particles of heliospheric origin.

Associations between coronal mass ejections and interplanetary shocks [PDF]
, 1983 Nearly continuous complementary coronal observations and interplanetary plasma measurements for the years 1979-1982 are compared. It is shown that almost all low latitude high speed coronal mass ejections (CME's) were associated with shocks at HELIOS 1 ...
