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,…
Intermittent Electron-Only Reconnection at Lunar Mini-Magnetospheres
Adam Stanier, Li-Jen Chen, Ari Le +2
Lunar crustal magnetic anomalies (LCMA) are sub-ion-gyroradius structures that have been shown to stand off the solar wind (SW) plasma from the Moon's surface, forming shock-like d…
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…
Multi-scale observation of magnetotail reconnection onset: 2. microscopic dynamics
K. J. Genestreti, C. Farrugia, S. Lu +23
We analyze the local dynamics of magnetotail reconnection onset using Magnetospheric Multiscale (MMS) data. In conjunction with MMS, the macroscopic dynamics of this event were cap…
Multi-scale observation of magnetotail reconnection onset: 1. macroscopic dynamics
K. J. Genestreti, C. Farrugia, S. Lu +22
We analyze a magnetotail reconnection onset event on 3 July 2017 that was observed under otherwise quiescent magnetospheric conditions by a fortuitous conjunction of six space and…
