How Common is Energetic ^3He in the Inner Heliosphere? [PDF]

, 2003
Using data from the SIS and ULEIS instruments on the Advanced Composition Explorer (ACE) we have identified periods during which energetic ^3He is present in near-Earth interplanetary space between November 1997 and May 2002.

Large‐Scale Magnetosheath Jets Formed by Shock‐Discontinuity Interactions: A Three‐Dimensional Global Hybrid Simulation

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Magnetosheath high‐speed jets with enhanced dynamic pressure are common in Earth's magnetosheath and can impinge on the magnetopause, driving pronounced boundary deformation. Recent observations indicate that shock–discontinuity interactions (SDIs) can generate magnetosheath jets, but the formation mechanism is still unclear.

MHD waves at the pre-front of interplanetary shocks on September 6 and 7, 2017

Solar-Terrestrial Physics
We analyze strong space weather disturbances during first ten days of September 2017, using the geomagnetic Dst index, parameters of normals to interplanetary shock fronts, direct measurements of interplanetary magnetic field, solar wind, and cosmic ray ...

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${

Soft X‐Ray Emission From Saturn's Magnetosheath Part I: 3D Modeling From MHD Data

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Saturn's magnetosheath hosts a mixed population of water‐group neutrals and solar wind plasma. We present a 3‐D model of soft X‐ray emission by ion‐neutral charge exchange in the near‐equatorial magnetosheath. The model employs MHD simulation data of plasma properties at Saturn, Enceladus‐genic neutral populations extrapolated from existing ...

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 ...

Interactions of energetic electrons with ULF waves triggered by interplanetary shock: Van Allen Probes observations in the magnetotail [PDF]

, 2014
We present in situ observations of a shock-induced substorm-like event on 13 April 2013 observed by the newly launched Van Allen twin probes. Substorm-like electron injections with energy of 30-500 keV were observed in the region from L∼5.2 to 5.5 ...

Shock waves propagation in the turbulent interplanetary plasma [PDF]

Advances in Space Research, 1996
AbstractEffect of turbulence on interplanetary shock waves propagation is considered. It is shown that background turbulence results in the additional shock wave deceleration which may be comparable with the deceleration due to plasma sweeping. The turbulent deceleration is connected with the energy losses due to the strong turbulence amplification ...

Investigating Magnetosphere‐Ionosphere‐Thermosphere Coupling During Geomagnetic Storms With a Novel Thermospheric Disturbance Index

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract This study introduces a novel thermospheric disturbance index, JpT ${J}_{p}^{T}$, designed to describe density variations during geomagnetic storms. The index is constructed by applying the spectral whitening method to thermospheric density data derived from precise orbit determination of satellites from 2015 to 2019.
