Demonstration of line-profile variations by means of prominent metal lines: the black solid, red dashed, and blue dash-dotted lines are observed Uves spectra with spectral resolutions R = 77 810 (Mg ii) and R = 107 200 (Fe ii, Si ii, and C ii) taken three and two days apart (MJD 51 707.23, 51 710.24, and 51 712.24). All lines – we note that Mg ii is a blend of two lines of similar strength – show the same temporal and morphologic changes, which resemble those of SPB stars.
