Spectroscopic time series of two nights of observations blueward of the Ca II K-line, calibrated using the reference spectrum. The observing sequences both lasted for about 6 hours and took place 24 hours apart. The disk line is near 0 km/s, and a strong blueshifted exocomet feature absorbs near –30 km/s on both nights, decelerating toward smaller blueshifts. In the second night, a third component appears statically near –40 km/s that blends with the decelerating feature. This component is indicated with the- dashed line. The line parameters of these exocomets are shown in Fig. 10.
