Zhang, Y. Hu, J. C. Tello\n(IAA-CSIC), S. B. Pandey (ARIES) and G. Lombardi (GTC La Palma), on behalf\nof a larger collaboration, report:\n\n�Following the detection of GRB 160629A by INTEGRAL (Gotz et al. GCNC\n19621), optical spectra of the optical counterpart (Klotz et al. GCNC\n19622, Sokolov et al. GCNC 19623) were obtained at both the 6.0m BTA\ntelescope in Zelenchuk (Russia) and at the 10.4m GTC in La Palma (Spain)\nstarting at 22.57 (June 29) and 4:39 (June 30) UT (i.e. 0.6 and 8.3 hr\npostburst) respectively. A preliminary analysis shows a deep Lyman-alpha\ntrough and several metal absorption lines (SiII, SiII*, CII, SiIV, CIV,\nFeII, and AlII, amongst others) at a common redshift of z = 3.332, which\nwe propose to be the redshift of the GRB host galaxy.\"",
