Jesper Sollerman (DARK, NBI;  U. Stockholm) report
on behalf of a larger collaboration:

Using FORS2 on the Very Large Telescope, we have obtained 
2*30 min spectra (grism 300V) of the optical afterglow 
of GRB 071112C (Perri et al., GCN 7059).

The spectrum displays numerous Fe II lines and the Mg II 
doublet (2796,2803) in absorption corresponding to a redshift 
of z = 0.823 (based on a preliminary wavelength calibration).
At this redshift we also find emission lines corresponding
to [O II] 3728 and [O III] 5008.

We thank the Paranal staff for excellent support, especially
Stephane Brillant and Linda Schmidtobreick.
