behalf of a larger collaboration:

"Using FORS1 on the ESO Very Large Telescope we obtained a 3x30 min
spectrum of the afterglow of GRB 060927 (GCNs #5627, 5629) on Sep 28.1.
We detect a sharp continuum break at 8070 A which we interpret as the
onset of the Lyman-alpha forest. Hence the redshift of GRB 060927 is
z=5.6.

We have placed a finding chart and an image of the 2d-spectrum here:
