Spectra of Mg II lines h and k in the Balmer continuum full wavelength range of IRIS (50 Å) during and after the mini flare times at the reconnection site along the first slit position (Figs. 2 a–c). Bidirectional outflows are observed at the reconnection point (y = 80 in panel a). Balmer continuum emission is visible in the three panels at two different pixels (y = 70, 80) in wavelengths 10 Å far from the k line core (see in panel b the two horizontal blue arrows). Blueshifts and redshifts, indicated by two white arrows in the Mg II k line wings, correspond to the twisted expelled jet and material falling back (panels a and c).
