Castro-Tirado (IAA-CSIC Granada), A. de Ugarte Postigo\n(ESO, INAF/OAB), on behalf of a larger collaboration, report:\n\nWe have observed the field of GRB090618 (Schady et al.,\nGCN 9512) with the 6-m telescope of the SAO RAS in\nCaucasus. We obtained B, Rc and Ic images as well as a\nlow-resolution spectrum under non favorable weather conditions.\nThe range and resolution of the spectrum were 3900-9200AA\nand FWHM=15-17A, respectively. A preliminary processing of\nthe spectrum showed a faint emission line at 5748.55A which we\ninterpret as [OII] 3727A. A corresponding redshift of 0.54 is in\nfull agreement with one obtained by Cenko et al. (GCN 9518).\nBecause of strong night sky OH bands and low resolution of the\nspectrum we could not clearly detect expected Hbeta and\n[OIII]4959,5007A lines. The photometry was calibrated using a\nnumber of SDSS stars in the field. Below we present a summary\nof some of our observations:\n\n               middle date, UT         results\n   -------------------------------------------------------\n   spectrum   19.977 June 2009      [OII]3727A detection\n          Rc     19.941 June 2009      20.51 +/- 0.06\n\nThis message can be cited.",
