A Major Geomagnetic Storm in 2024 October Linked to Sympathetic CME--Prominence Eruptions
Rui Wang, Huidong Hu, Xiaowei Zhao +11
Improving predictions of the geomagnetic impact of coronal mass ejections (CMEs) requires understanding how solar source properties relate to in-situ measurements at Earth. However…
Lateral Deformation of Large-scale Coronal Mass Ejections during the Transition from Non-radial to Radial Propagation
Huidong Hu, Chong Chen, Yiming Jiao +4
Many coronal mass ejections (CMEs) initially propagate non-radially, and then transition to radial propagation in the corona. This directional transition is a significant process t…
A Pileup of Coronal Mass Ejections Produced the Largest Geomagnetic Storm in Two Decades
Ying D. Liu, Huidong Hu, Xiaowei Zhao +2
The largest geomagnetic storm in two decades occurred in 2024 May with a minimum of nT. We examine its solar and interplanetary origins by combining multipoint…
Limb Observations of Global Solar Coronal Extreme-ultraviolet Wavefronts: The Inclination, Kinematics, Coupling with the Expanding Coronal Mass Ejections, and Connection with the Coronal Mass Ejection Driven Shocks
Huidong Hu, Bei Zhu, Ying D. Liu +3
We select and investigate six global solar extreme-ultraviolet (EUV) wave events using data from the Solar Dynamics Observatory and the Solar and Heliospheric Observatory. These er…
Formation of a Magnetic Cloud from the Merging of Two Successive Coronal Mass Ejections
Chong Chen, Ying D. Liu, Bei Zhu +2
On 2022 March 28 two successive coronal mass ejections (CMEs) were observed by multiple spacecraft and resulted in a magnetic cloud (MC) at 1 AU. We investigate the propagation and…
The Alpha-Proton Differential Flow in the Alfvénic Young Solar Wind: From Sub-Alfvénic to Super-Alfvénic
Hao Ran, Ying D. Liu, Chong Chen +1
Data obtained from Parker Solar Probe (PSP) since 2021 April have shown the first in situ observation of the solar corona, where the solar wind is formed and accelerated. Here we i…
Multispacecraft Remote Sensing and In Situ Observations of the 2020 November 29 Coronal Mass Ejection and Associated Shock: From Solar Source to Heliospheric Impacts
Chong Chen, Ying D. Liu, Bei Zhu
We investigate the source eruption, propagation and expansion characteristics, and heliospheric impacts of the 2020 November 29 coronal mass ejection (CME) and associated shock, us…
Analysis of the distribution, rotation and scale characteristics of solar wind switchbacks: comparison between the first and second encounters of Parker Solar Probe
Mingming Meng, Ying D. Liu, Chong Chen +1
The S-shaped magnetic structure in the solar wind formed by the twisting of magnetic field lines is called a switchback, whose main characteristics are the reversal of the magnetic…
Determination of Solar Wind Angular Momentum and Alfvén Radius from Parker Solar Probe Observations
Ying D. Liu, Chong Chen, Michael L. Stevens +1
As fundamental parameters of the Sun, the Alfvén radius and angular momentum loss determine how the solar wind changes from sub-Alfvénic to super-Alfvénic and how the Sun spins dow…
Characteristics and Importance of "ICME-in-Sheath" Phenomenon and Upper Limit for Geomagnetic Storm Activity
Ying D. Liu, Chong Chen, Xiaowei Zhao
As an important source for large geomagnetic storms, an "ICME-in-sheath" is a completely shocked interplanetary coronal mass ejection (ICME) stuck in the sheath between a shock and…
Characteristics of a Gradual Filament Eruption and Subsequent CME Propagation in Relation to a Strong Geomagnetic Storm
Chong Chen, Ying D. Liu, Rui Wang +3
An unexpected strong geomagnetic storm occurred on 2018 August 26, which was caused by a slow coronal mass ejection (CME) from a gradual eruption of a large quiet-region filament.…
