Johan P.U. Fynbo, Jens Hjorth (DARK, NBI), Rhaana Starling
(U. Amsterdam), D. Alexander Kann (TLS Tautenburg) and
Dieter Hartmann (Clemson University) report on behalf of a
larger collaboration:

Using FORS1 on the Very Large Telescope, we have obtained
3*30 min spectra (300V) of GRB 060714 (Krimm et al., GCN 5311).
The acquisition image shows the UVOT optical afterglow candidate
to have R ~ 20.4 on July 14.990 (8.54 hours post-burst).

The combined spectrum is rich of absorption features, including
Ly-alpha, Ly-beta, S II, C II, C IV, Si II, Si IV, Fe II, Al II
and Zn II, corresponding to a redshift of z = 2.71.
