Automatic detection of Flare Ribbon Fine Structures as Proxies for Plasmoid Dynamics in Flare Reconnection
Georgios Chouliaras, Peter F. Wyper, Joel T. Dahlin +1
Flare ribbons often display fine structures along their fronts that are commonly interpreted as signatures of intermittent reconnection dynamics including plasmoid formation in the…
Extremely energetic EUV late phase of a pair of C-class flares caused by a non-eruptive sigmoid
Ya Wang, Sargam M. Mulay, Lyndsay Fletcher
The EUV late phase is the second increase of the irradiance of the warm coronal lines during solar flares, and has a crucial impact on the Earth's ionosphere. In this paper, we rep…
Magnetic Dip Found in a Quiescent Prominence Foot via Observation and Simulation
Huadong Chen, Chun Xia, Suli Ma +8
Solar prominences (or filaments) are cooler and denser plasma suspended in the much hotter and rarefied solar corona. When viewed on the solar disc filament barbs or feet protrude…
High-resolution observational analysis of flare ribbon fine structures
Jonas Thoen Faber, Reetika Joshi, Luc Rouppe van der Voort +4
Context. Since the mechanism of energy release from solar flares is still not fully understood, the study of fine-scale features developing during flares becomes important for prog…
Simultaneous Eruption and Shrinkage of Pre-existing Flare Loops during a Subsequent Solar Eruption
Huadong Chen, Lyndsay Fletcher, Guiping Zhou +6
We investigated two consecutive solar eruption events in the solar active region (AR) 12994 at the solar eastern limb on 2022 April 15. We found that the flare loops formed by the…
Photospheric signatures of CME onset
Aslam Ottupara, David MacTaggart, Tom Williams +2
Coronal mass ejections (CMEs) are solar eruptions that involve large-scale changes to the magnetic topology of an active region. There exists a range of models for CME onset which…
