GCN 17688, Ivanov et al. GCN 17689) obtained by the Asiago Transient \nClassification Program (Tomasella et al. 2014, AN, 335, 841) with the Asiago \n1.82 m Copernico Telescope +AFOSC (Tomasella et al. ATel 7391). In addition \nto the Ly-alpha feature already reported, we identify absorption features of SiII, \nSiII*, CII, SiIV, CIV, FeII and AlII at a common redshift of 3.139+/-0.003, slightly \nlower than previously reported by Sanchez-Ram�rez (GCN 17697) and by \nTomasella et al. (ATel 7391). In addition we report a tentative detection of a MgII \nintervening absorber at z=0.950+/-0.003.",
