Evidence for plasmoid formation related to a hot UV burst in the solar atmosphere
Mats Ola Sand, Luc Rouppe van der Voort, Souvik Bose +4
Magnetic reconnection in the solar atmosphere drives energetic phenomena such as Ellerman bombs, UV bursts, and surges. We used coordinated observations from the Swedish 1-m Solar…

Active chromospheric fibril singularity: Coordinated observations from Solar Orbiter, SST, and IRIS
Reetika Joshi, Luc Rouppe van der Voort, Guillaume Aulanier +6
The fine structures of the solar chromosphere, driven by photospheric motions, play a crucial role in the dynamics of solar magnetic fields. Many have been already identified such…

Fine details in solar flare ribbons: Statistical insights from observations with the Swedish 1-m Solar Telescope
Jonas Thoen Faber, Reetika Joshi, Luc Rouppe van der Voort +4
Flare ribbons serve as chromospheric footprints of energy deposition resulting from particle acceleration during magnetic reconnection. Their fine-scale structure provides a valuab…
