Stella (INAF/OArm), \nreport on behalf of the MISTICI collaboration:\n\nWe observed the optical afterglow (Torii, GCN 3943; Cenko, Fox & Berger, \nGCN 3944) of GRB 050908 (Goad et al., GCNs 3942, 3946) with the ESO-VLT \nUT2, equipped with the FORS1 instrument. Spectroscopy was performed with \nthe grism 300V, covering the wavelength range 4500-8500 AA. Twenty \nminutes of exposure were acquired starting on 2005 Sep 8, 07:19 UT. Data \nreduction was performed using archivial calibration files, so that small \nsystematic uncertainties may be present in our analysis.\n\nBased on the detection of Lyalpha, SiIV1309,1402, CIV1548,1550, \nSiII1206, and the Lyman limit, we measure a redshift z = 3.350 +- 0.005.\n\nFurther analysis is in progress and results will be communicated later.\n\nWe acknowledge the outstanding support received from the ESO staff.\n\nThis message can be cited.\n\n[GCN OPS NOTE(10sep05): Per author's request, \"N.
