Interplanetary shock induced intensification of electron cyclotron harmonic waves in the Earth’s inner magnetosphere

Frontiers in Physics
Electron cyclotron harmonic (ECH) waves are electrostatic emissions frequently observed in the Earth’s magnetosphere. By precipitating magnetospheric hot electrons into the ionosphere, ECH waves play a critical role in the formation of diffuse aurora ...

Formation of H+ PUI Tails Downstream of Distant Interplanetary Shocks

The Astrophysical Journal
New Horizons’ Solar Wind Around Pluto (SWAP) instrument has observed interplanetary shocks from ∼20 to 60 au from the Sun. Different studies have analyzed the effects of these shocks on the solar wind ion (SWI) and interstellar pickup ion (PUI ...

Interplanetary Causes and Impacts of the 2024 May Superstorm on the Geosphere: An Overview

The Astrophysical Journal
The recent superstorm of 2024 May 10–11 is the second largest geomagnetic storm in the space age and the only one that has simultaneous interplanetary data (there were no interplanetary data for the 1989 March storm). The May superstorm was characterized

Parker Solar Probe Observations of Turbulence and Waves between a Current Sheet and an Interplanetary Coronal Mass Ejection–Driven Shock

The Astrophysical Journal
We report on unusual magnetic wave activity seen in a region between the crossing of a current sheet and an interplanetary shock by the Parker Solar Probe (PSP).

MHD waves in the pre-front region of the interplanetary shock on May 10, 2024

Solar-Terrestrial Physics
The article reports on the study of the dynamics of the IMF turbulent component from the quiet period on May 7, 2024 to the arrival of an interplanetary shock wave in the second half of May 10, 2024.

Post-shock spikes: A new feature of proton and alpha enhancements associated with an interplanetary shock wave [PDF]

Abrupt and prolonged enhancements in the intensities of 100 to approximately 2000 keV nucleon protons and alpha particles observed in interplanetary space are interpreted as particle populations confined between an interplanetary shock front and a ...

Electron Acceleration at Shock Ripples: Role of Pitch-angle Diffusion

The Astrophysical Journal
Suprathermal electrons are routinely observed in interplanetary space. At higher energies, there are in-situ evidences that shocks, both interplanetary shocks, often driven by fast coronal mass ejections, and terrestrial bow shocks, can accelerate ...

Helium Pickup Ion Velocity Distributions Observed in Interplanetary Coronal Mass Ejection Structures

The Astrophysical Journal
The velocity distribution functions (VDFs) of He ^+ pickup ions (PUIs) through two interplanetary coronal mass ejection (ICME) events associated with two interplanetary shocks are examined.
