Coronal structure and dynamics

"Coronal dimmings, also called transient coronal holes, are well documented following eruptions (e.g. Veronig et al. 2025). Between 17 and 18 March 2022, a coordinated Solar Orbiter–Hinode–IRIS campaign monitored the formation of a coronal dimming following a filament eruption (Ngampoopun et al. 2023).
We investigate whether the eruption produced a coronal-hole-like behaviour in the initially...
