Chincarini (Univ. \nMilano-Bicocca) and L. Stella (INAF/OAR), on behalf of the MISTICI collaboration, report:\n\nUsing the FORS1 instrument at the ESO VLT, we obtained a spectrum of the \nobject indicated by Antonelli et al. (GCN 3666), also named as object B \nby Bloom et al. (GCN 3672). This object is liying close to the XRT \nerrorbox center (Covino et al., GCN 3665; Romano et al., GCN 3669). \nObservations were obtained on 2005, July 24, starting at 23:16:00 \nUT, under good seeing conditions. We used the grism 300V with a slit of \n1.0 arcsec. The integration time was 900 s.\n\n\nThe object is identified with a star trough Ca, CN, G-band, Hbeta, Na \nand Halpha faint absorption lines. It has therefore no likely \nassociation with GRB 050724.\n\nWe thank the excellent work by the ESO staff in performing these \nobservations.\n\nThis message may be cited.\n\n[GCN OPS NOTE(28jul05):  Per author's request, in the Subject-line\nthe \"GRB 050624\" was changed to \"GRB 050724\".]",
