First Results of Calculation of the Dayside Magnetopause Reconnection Rate with TRACERS
D. E. da Silva, L. J. Chen, B. Burkholder +14
Quantifying the rate of reconnection remains a key challenge in the study of geomagnetic storms. In this study, we present the first results from the new Tandem Reconnection and Cu…
The May 2024 Storm: dayside magnetopause and cusps in simulated soft X-Rays
J. Ng, L. -J. Chen, B. Burkholder +10
The coronal mass ejection (CME) arriving at Earth on May 10, 2024 caused the most intense geomagnetic storm in the last two decades, and resulted in highly unusual magnetopause and…
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 turbul…
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 sto…
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. For…
Earth's Alfvén Wings: Unveiling Dynamic Variations of Field-line Topologies with Electron Distributions
Harsha Gurram, Jason R. Shuster, Li-Jen Chen +6
The magnetic cloud (MC) of the Coronal Mass Ejection on April 24, 2023, contains sub-Alfvénic solar wind, transforming Earth's magnetosphere from conventional bow-shock magnetotail…
Turbulence properties and kinetic signatures of electron in Kelvin-Helmholtz waves during a geomagnetic storm
Harsha Gurram, Jason R. Shuster, Li-Jen Chen +5
We present a comprehensive study of Magnetospheric Multiscale (MMS) spacecraft encounter with KHI during a geomagnetic storm, focusing on elucidating key turbulence properties and…
Field-Aligned Current Structures during the Terrestrial Magnetosphere's Transformation into Alfven Wings and Recovery
Jason M. H. Beedle, Li-Jen Chen, Jason R. Shuster +8
On April 24th, 2023, a CME event caused the solar wind to become sub-Alfvenic, leading to the development of an Alfven Wing configuration in the Earth's Magnetosphere. Alfven Wings…
Interplanetary magnetic field controlled Alfvén wings at Earth during encounter of a coronal mass ejection
Yuxi Chen, Chuanfei Dong, Li-Jen Chen +2
In the vicinity of Earth's orbit, the typical solar wind Alfvén Mach number exceeds 5, and the super-Alfvénic solar wind drives a conventional magnetosphere configuration. However,…
Earth's Alfvén wings driven by the April 2023 Coronal Mass Ejection
Li-Jen Chen, Daniel Gershman, Brandon Burkholder +33
We report a rare regime of Earth's magnetosphere interaction with sub-Alfvénic solar wind in which the windsock-like magnetosphere transforms into one with Alfvén wings. In the mag…
