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…
Unveiling Key Factors in the Solar Eruptions Leading to the Solar Superstorm in 2024 May
Rui Wang, Ying D. Liu, Xiaowei Zhao +1
NOAA Active Region (AR) 13664/8 produced the most intense geomagnetic effects since the ``Halloween'' event of 2003. The resulting extreme solar storm is believed to be the consequ…
High-resolution Observations of Clustered Dynamic Extreme-Ultraviolet Bright Tadpoles near the Footpoints of Corona Loops
Rui Wang, Ying D. Liu, L. P. Chitta +2
An extreme ultraviolet (EUV) close-up view of the Sun offers unprecedented detail of heating events in the solar corona. Enhanced temporal and spatial images obtained by the Solar…
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…
Direct In Situ Measurements of a Fast Coronal Mass Ejection and Associated Structures in the Corona
Ying D. Liu, Bei Zhu, Hao Ran +6
We report on the first direct in situ measurements of a fast coronal mass ejection (CME) and shock in the corona, which occurred on 2022 September 5. In situ measurements from the…
Observations of Mini Coronal Dimmings Caused by Small-scale Eruptions in the Quiet Sun
Rui Wang, Ying D. Liu, Xiaowei Zhao +1
Small-scale eruptions could play an important role in coronal heating, generation of solar energetic particles (SEPs), and mass source of the solar wind. However, they are poorly o…
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.…
Quantifying the Propagation of Fast Coronal Mass Ejections from the Sun to Interplanetary Space Combining Remote Sensing and Multi-Point in-situ Observations
Xiaowei Zhao, Ying D. Liu, Huidong Hu +1
In order to have a comprehensive view of the propagation and evolution of coronal mass ejections (CMEs) from the Sun to deep interplanetary space beyond 1 au, we carry out a kinema…
A Comparative Study of 2017 July and 2012 July Complex Eruptions: Are Solar Superstorms "Perfect Storms" in Nature?
Ying D. Liu, Xiaowei Zhao, Huidong Hu +2
It is paramount from both scientific and societal perspectives to understand the generation of extreme space weather. We discuss the formation of solar superstorms based on a compa…
Geometry, Kinematics and Heliospheric Impact of a Large CME-driven Shock in 2017 September
Ying D. Liu, Bei Zhu, Xiaowei Zhao
A powerful coronal mass ejection (CME) occurred on 2017 September 10 near the end of the declining phase of the historically weak solar cycle 24. We obtain new insights concerning…
A Solar Eruption with Relatively Strong Geo-effectiveness Originating from Active Region Peripheral Diffusive Polarities
Rui Wang, Ying D. Liu, Huidong Hu +1
We report the observations of a moderate but relatively intense geo-effective solar eruption on 2015 November 4 from the peripheral diffusive polarities of active region 12443. We…
A Stealth CME Bracketed between Slow and Fast Wind Producing Unexpected Geo-effectiveness
Wen He, Ying D. Liu, Huidong Hu +2
We investigate how a weak coronal mass ejection (CME) launched on 2016 October 8 without obvious signatures in the low corona produced a relatively intense geomagnetic storm. Remot…
