Statistical Analysis of Minifilament Eruptions Using Full-disk H Blue-wing Observations at Big Bear Solar Observatory
Artin Khaleghi, Qin Li, Nengyi Huang +2
This paper presents a comprehensive statistical analysis of minifilament eruptions (MFEs) using high-cadence full-disk H blue-wing observations from Big Bear Solar Observatory.…
Stereoscopic Observations of Solar X-ray Sources Explained by a Data-Constrained Magnetohydrodynamic Simulation
Keitarou Matsumoto, Satoshi Inoue, Meiqi Wang +6
We investigated the three-dimensional (3D) magnetic structures and dynamics responsible for particle acceleration in an X7.1-class flare that occurred on October 1, 2024, in NOAA a…
Spatial and Dynamical Relations between Spicules and Network Bright Points
Jeongwoo Lee, Eun-Kyung Lim, Viggo Hansteen
Spicules are among the most ubiquitous small-scale, jet-like features in the solar chromosphere and are widely believed to play a significant role in transporting mass and energy i…
Driving mechanisms of solar active region geysers: The role of interacting magnetic flux
Aabha Monga, Satoshi Inoue, Jeongwoo Lee +2
Active region recurrent jets are manifestations of episodic magnetic energy release processes driven by complex interactions in the lower solar atmosphere. While magnetic flux emer…
Fine Structures of Tiny Quiet Sun Jets Observed by Solar Orbiter and Big Bear Solar Observatory
Jeongwoo Lee, Dana Longcope, Junmu Youn +3
We present the first joint high-resolution observations of small-scale EUV jets using Solar Orbiter(SolO)'s Extreme Ultraviolet Imager and High Resolution Imager (HRI) and H im…
A Data-constrained Magnetohydrodynamic Simulation of Successive X-class Flares in Solar Active Region 13842. II. Dynamics of the Solar Eruption Associated with the X9.0 Solar Flare
Keitarou Matsumoto, Satoshi Inoue, Keiji Hayashi +5
Active region NOAA 13842 produced two successive solar flares: an X7.1-class flare on October 1, 2024, and an X9.0-class flare on October 3, 2024. This study continues our previous…
