Fynbo (DARK/NBI)\nreport on behalf of a larger collaboration,\n\nWe have observed the field of GRB 090814A (Ukwatta et al. GCN 9793)\nusing FORS2 at the VLT (Paranal observatory) starting at 02:05 UT\n(70 minutes after the burst). We detect the object identified by  \nUpdike et\nal. (GCN 9794) with a magnitude of R~21.5.\n\nThe spectrum shows continuum down to at least 3900 Angstroms.\nNon detection of Ly-alpha implies a limit of z < 2.2. We identify a\nweak absorption system at z=0.696 through the detection of MgII and  \nCaII.\nThis is therefore likely to be the redshift of the GRB but we note that\nit could also be produced by an intervening system and thus the strict\nredshift range for this GRB would be 0.696 < z < 2.2.\n\nWe acknowledge the excelent support from Parnal observatory, in\nparticular J. Smoker and L. Rivas.",
