Ca II K (left panel, resolution 0.016 Å pixel−1), Fe II 5169 Å (middle, resolution 0.03 Å pixel−1)), Hα(right, resolution 0.01 Å pixel−1). Spectra were taken with HARPS-N during the night of 2019-01-29/30; each spectrum is 15 min apart starting 01h01m UT (first spectrum at the top) and finishing 04h07m UT (last spectrum at the bottom). The dashed line corresponds to a velocity of 3 km s−1.
