SALT spectrum of our 2020 observation of PKS 0903-57. The spectrum shows prominent stellar absorption lines and a strong NaID interstellar absorption feature. No emission feature possibly linked to the AGN is detected. In particular, we show in two insets the zoom of the wavelength regions where the features detected by Thompson et al. (1990) should lie. Only weak ripples are visible.
