GCN Circular 13532
N. R. Tanvir (U. Leicester) and J. Ball (Gemini) report on behalf of a larger collaboration: We observed the afterglow of GRB 120729A (Ukwatta et al. GCN 13530) using the GMOS-N spectrograph on Gemini-North. Observations began at 2012-7-29 12:11 UT, about 75 mins post-burst. The spectrum reveals strong absorption lines of MgI, MgII, FeII, MnII. A provisional reduction gives a redshift of z=0.80, which we believe is most likely the redshift of this burst.
