The evolution of CME sheath turbulence from L1 to Earth: Wind and MMS observations of the 2023-04-23 CME
Matthew R. Argall, Li-Jen Chen, Noé Lugaz +5
An interplanetary shock driven by a coronal mass ejection (CME) containing an interval of sub-Alfvénic flow impacted Earth on April 23, 2024. In this article, we analyze the turbu…

Field Aligned Currents and Auroral Precipitation During the Terrestrial Alfven Wing State
Brandon Burkholder, Li-Jen Chen, Kareem Sorathia +3
When sub-Alfvénic (Alfvén Mach number MA < 1) plasmas impact Earth, Alfvén wings (AWs) develop. A Multiscale Atmosphere Geospace Environment (MAGE) simulation of the April 2023…

Observation of O+ Characteristics During the Terrestrial Alfvén Wing State Induced by the April 2023 Coronal Mass Ejection
Haoming Liang, Li-Jen Chen, Stephen A. Fuselier +7
We report Magnetospheric Multiscale observations of oxygen ions (O+) during a coronal mass ejection in April 2023 when the solar wind was sub-Alfvénic and Alfvén wings formed. Fo…
