Abstract: Context. The Solar Orbiter mission completed its first remote-sensing observation windows in the spring of 2022. On 2 April 2022, an M-class flare followed by a filament eruption was seen both by the instruments on board the mission and from several observatories in Earth’s orbit, providing an unprecedented view of a flaring region with a large range of observations. Aims. We aim to understand the nature of the flaring and filament eruption events via the analysis of the available dataset. The complexity of th… Show more

“…This result is fully consistent with what was already known about homologous flares: the magnetic configuration remains similar between successive flares and is reformed between flare events. Such flares are readily explained by the reconnection of coronal magnetic fields, resulting in flare ribbons in the chromosphere (Sui et al, 2004;Liu et al, 2014;Janvier et al, 2023), which is now considered the standard model in solar physics. The energized field is in the form of a sheared core or filament channel, which persists or reforms by shearing motions after subsequent flares (Manchester, 2003;Romano et al, 2018).…”
