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. Fo…
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 m…
