report, on behalf of the MISTICI collaboration:
We observed the optical afterglow of GRB 081008 (Rykoff, GCN 8343;
Racusin et al., GCN 8344), with the ESO VLT on Oct 09 starting about 4.5
hours after the burst with UVES. In the UVES spectrum we clearly detect
the Ly-alpha around lambda 3600 A at a redshift z = 1.96, further
analysis of this spectrum are ongoing. In light of this, from a refined
analysis of our VLT/FORS2 spectrum of this GRB (D'Avanzo et al. GCN
8345), we can identify the metal lines reported by Cucchiara et al. (GCN
8346) and the absorption lines CrII(2056, 2062,2066) and ZnII(2062) all
at a redshift z = 1.9685.
Our results are thus in agreement with what reported by Cucchiara et al.
