Interplanetary magnetic field rotations followed from L1 to the ground : the response of the Earth's magnetosphere as seen by multi-spacecraft and ground-based observations [PDF]

, 2011
A study of the interaction of solar wind magnetic field rotations with the Earth's magnetosphere is performed. For this event there is, for the first time, a full coverage over the dayside magnetosphere with multiple (multi)spacecraft missions from dawn ...

Observations of the response time of high-latitude ionospheric convection to variations in the interplanetary magnetic field using EISCAT and IMP-8 data [PDF]

, 1999
International audienceWe have combined ~300 h of tristatic measurements of the field-perpendicular F region ionospheric flow measured overhead at Tromsø by the EISCAT UHF radar, with simultaneous IMP-8 measurements of the solar wind and interplanetary ...

Plasmaspheric High‐Frequency Whistlers as a Candidate Cause of Shock Aurora at Earth

Geophysical Research Letters, 2023
Auroral brightening driven by interplanetary shocks on Earth's closed magnetic field lines is commonly attributed to the 0.1–10 keV electron precipitations by electron cyclotron harmonic waves and whistler‐mode chorus waves in the low‐density region.

Reconnection in a rotation-dominated magnetosphere and its relation to Saturn's auroral dynamics [PDF]

, 2005
peer reviewed[1] The first extended series of observations of Saturn's auroral emissions, undertaken by the Hubble Space Telescope in January 2004 in conjunction with measurements of the upstream solar wind and interplanetary magnetic field ( IMF) by the

Multi-spacecraft observations of shocklets at an interplanetary shock [PDF]

, 2023
Interplanetary (IP)shocks are fundamental building blocks of the heliosphere, and the possibility to observe them in situ is crucial to address important aspects of energy conversion for a variety of astrophysical systems.

Arrival times of Flare/Halo CME associated shocks at the Earth: comparison of the predictions of three numerical models with these observations [PDF]

Annales Geophysicae, 2002
The arrival times at L1 of eleven travelling shocks associated both with X-ray flaring and with halo CMEs recorded aboard SOHO/LASCO have been considered.

Dynamics of He⁺⁺ Ions at Interplanetary and Earth’s Bow Shocks

Universe, 2022
Experimental investigations of the fine plasma structure of interplanetary shocks are extremely difficult to conduct due to their small thickness and high speed relative to the spacecraft.

Compression of the Earth's magnetotail by interplanetary shocks directly drives transient magnetic flux closure [PDF]

, 2006
peer reviewedWe use a novel method to evaluate the global opening and closure of magnetic flux in the terrestrial system, and to analyse two interplanetary shock passages that occurred during magnetically quiet periods.

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?
