High temporal- and spatial-resolution photographs of the “Christmas” red-green auroras taken over Germany during a main phase of the 10–11 May 2024 superstorm

Abstract. High spatial and temporal resolution images of red auroras over Germany during the 10–11 May 2024 magnetic storm have added new information concerning stable auroral red (SAR) arc formation. The high-altitude red aurora displayed brightness streaks/rays, which continued...

Connectivity rewiring and filament formation by active region emergence observed with Solar Orbiter

Using an 11-day dataset from Solar Orbiter, combining EUV imaging, Hα observations, vector magnetograms and nonlinear force-free field extrapolations, we track the evolution from the emergence of a new active region to the reconfiguration of coronal connectivity. We find that the...
