The physics of space weather/solar-terrestrial physics (STP): what we know now and what the current and future challenges are [PDF]

open access: yesNonlinear 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?

Interplanetary shock-associated aurora [PDF]

open access: yes, 2019
Interplanetary shocks or solar wind pressure pulses have prompted impacts on Earth’s magnetospheric and ionospheric environment, especially in causing dynamic changes to the bright aurora in the polar ionosphere.

Observations of ionospheric flows and particle precipitation following a Sudden Commencement [PDF]

open access: yesAnnales 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 ...

Multispacecraft observations of the terrestrial bow shock and magnetopause during extreme solar wind disturbances [PDF]

open access: yesAnnales 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.

Simultaneous interplanetary scintillation and Heliospheric Imager observations of a coronal mass ejection [PDF]

open access: yes, 2008
We describe simultaneous Interplanetary Scintillation (IPS) and STEREO Heliospheric Imager (HI) observations of a coronal mass ejection (CME) on 16 May 2007. Strong CME signatures were present throughout the IPS observation.

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

open access: yesSolar-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 ...

Properties of a Supercritical Quasi-perpendicular Interplanetary Shock Propagating in the Terrestrial Foreshock Region

open access: yes, 2022
International audienceWe investigate the properties of an interplanetary (IP) shock (M f = 2.1, θ = 80°) that was detected by Wind on 1999 September 12 and was magnetically connected to the terrestrial bow shock.

The event of 21 June 1980 and the origin of solar cosmic rays [PDF]

open access: yesGeofísica Internacional, 2000
We present well-observed interplanetary disturbances in the near Earth environment and discuss their behavior. From these observations a hypothetical two source origin of Solar Cosmic Rays is discussed.

Evidence for transient, local ion foreshocks caused by dayside magnetopause reconnection [PDF]

open access: yesAnnales 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.
