Amsterdam) report on behalf of the Stargate collaboration:\n\nWe observed the optical counterpart (Siegel et al., GCN 24889; Pozanenko\net al., GCN 24892) of GRB 190627A (Sonbas et al., GCN 24888) with the ESO\nVLT UT1 equipped with the FORS2 spectrograph. We obtained a 30 min spectrum\nwith the 600RI (512 - 845 nm) and a 30 min spectrum with the 600z (737-1070\nnm)\ngrism. Observations started at 01:12:41 UT on June 30 (i.e., 2.57 days\nafter the\nGRB detection).\n\nIn the spectrum, the continuum is clearly detected. We detect three MgII\nabsorption systems at redshifts z = 1.942, 1.774 and 1.681. The redshift\nz = 1.942 and 1.681 absorption systems also exhibit FeII lines. We conclude\nthat z = 1.942 is the likely redshift of GRB 190627A.\n\nWe acknowledge the ESO observing staff at Paranal, especially Karleyne Silva\nand Juan Carlos Munoz.",
