Malesani (DAWN/NBI and DARK/NBI) report on behalf \nof the Stargate collabaration:\n\nWe observed the optical afterglow (Marshall, GCN 23996) of GRB 190324A \n(LaPorte et al., GCN 23993) using the ESO VLT UT2 (Kueyen) equipped with \nthe X-shooter spectrograph. Our spectra cover the wavelength range \n3000-21000 AA, and consist of 2 exposures by 600 seconds each. The \nobservation mid time was 2019 Mar 25.0441 UT (2.324 hr after the GRB).\n\nWe detect continuum at high-S/N over the entire covered wavelength \nrange. A multitude of absorption features are detected, including Ca II, \nMg II, Mg I, Fe II, Al II, Cr II, all at a common redshift z = 1.1715. \nIn particular, fine structure lines from Fe II* are visible, which \nconfirm the association of the absorption system with the GRB.\n\nWe acknowledge excellent support from the ESO observing staff in \nParanal, in particular Romain Thomas, Anita Zanella, and Juan Carlos \nOlivares.",
