Vreeswijk\n(ESO) report:\n\nWe observed the OT (Rykoff et al., GCN 6497) of GRB 070611 (Stroh et al.,\nGCN 6494) with FORS2/VLT using grism 300V through thin clouds. 2x30 min\nspectra were acquired starting on June 11, UT 09:37.\n\nIn the spectra, we detect Lyman alpha, SiII, OI, CII, CIV and AlII from\nwhich we infer a redshift of z=2.04 for that burst. In addition, we detect Mg II\nand Fe II from an intervening system at z=1.29.\n\nWe thank the Paranal staff for excellent support, in particular Arjan Bik\nand Mario van den Ancker.",
