MMS Insights into CME Driven Sub-Alfvénic Solar Wind at 1 AU
Harsha Gurram, Li-Jen Chen, Matthew R. Argall +4
We report the properties of electron distributions and turbulence during a Coronal Mass Ejection (CME) in April 2023 observed by Magnetospheric Multiscale (MMS). The CME exhibits a…
Investigating the Dependence of Normalized Reconnection Rate on Upstream Plasma Parameters
S. V. Heuer, K. J. Genestreti, Y. -H Liu +4
We present the results of a multi-event study of the normalized reconnection rate integrating events spanning the three primary regimes of reconnection observed by the Magnetospher…
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…
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…
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…
