GCN 12454;\nusing the GMOS-S spectrograph on Gemini-South in good conditions.\n\nObservations began at 2012-7-12 23:43 UT, about 10 hr post-burst.\nThe spectrum reveals a clear Ly-a break, and many other absorption\nfeatures.  A provisional reduction gives a redshift of z=4.15, although\nthis figure will be refined with better calibration.",
