Overview image of the observation at 08:28 (upper set of panels) and 12:19 (lower set of panels). In each set of panels, the upper left panel shows the Hβ far wing image, the upper right panel the Hβ core forming in the chromosphere, the lower left panel shows the continuum image in Fe I 6302 Å and the lower right the line core of Ca II 8542 Å, also forming in the chromosphere. The black box indicates where we selected a subframe to invert the data with STiC.
