The physics of space weather/solar-terrestrial physics (STP): what we know now and what the current and future challenges are [PDF]
Nonlinear Processes in Geophysics, 2020 Major geomagnetic storms are caused by unusually intense solar wind southward magnetic fields that impinge upon the Earth's magnetosphere (Dungey, 1961). How can we predict the occurrence of future interplanetary events?

Multispacecraft observations of the terrestrial bow shock and magnetopause during extreme solar wind disturbances [PDF]
Annales Geophysicae, 2012 Three events are discussed from the declining phase of the last solar cycle when the magnetopause and/or the bow shock were observed unusually close to the Earth due to major interplanetary disturbances.

Acceleration of an interplanetary shock through the magnetosheath: a global hybrid simulation
Frontiers in Astronomy and Space SciencesAccording to most observations and simulations, interplanetary shocks slow down when they propagate through the magnetosheath. In this article, we present results from a self-consistent global hybrid PIC simulation of an interplanetary shock which, by ...

Observations of ionospheric flows and particle precipitation following a Sudden Commencement [PDF]
Annales Geophysicae, 2000 On May 4, 1998, at 0227 UT an interplanetary shock crossed the WIND spacecraft, and half an hour later a Sudden Commencement occurred. Coinciding with the Sudden Commencement a rapid intensification of the flux of particle precipitation into the ...

Interpretation of Flat Energy Spectra Upstream of Fast Interplanetary Shocks
The Astrophysical Journal, 2023 Interplanetary shocks are large-scale heliospheric structures often caused by eruptive phenomena at the Sun, and represent one of the main sources of energetic particles.

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

Evidence for transient, local ion foreshocks caused by dayside magnetopause reconnection [PDF]
Annales Geophysicae, 2016 We present a scenario resulting in time-dependent behaviour of the bow shock and transient, local ion reflection under unchanging solar wind conditions.

Single-spacecraft techniques for shock parameters estimation: A systematic approach
Frontiers in Astronomy and Space Sciences, 2022 Spacecraft missions provide the unique opportunity to study the properties of collisionless shocks utilising in situ measurements. In the past years, several diagnostics have been developed to address key shock parameters using time series of magnetic ...

Reflected ions at interplanetary shocks [PDF]
Geophysical Research Letters, 2010 This paper shows that the shock dissipation mechanism changes profoundly from the inner to outer heliosphere and that pickup ions are responsible for shock dissipation beyond 35 AU. We make the first study of reflected ions in ICME sheaths downstream of interplanetary shocks observed by Voyager 2 from 1–80 AU.
