Patat (ESO), on behalf of the GRACE collaboration, report:\n\n\"On 2006 February 21.051 UT we acquired a 30-min spectrum of the optical \ntransient associated with the possible GRB060218 (Cusumano et al., GCN\n4775) with VLT-Antu equipped with FORS2 and low resolution grating \n300V+GG435. We confirm the presence of narrow nebular lines at redshift\nz = 0.033 (Mirabal & Halpern, GCN 4792). We also note that the spectral\ncontinuum shows an overall shape which resembles that of supernova 1997ef \naround maximum (Iwamoto et al., 2000, ApJ, 534, 660).\n\nThis may suggest that, if this object is a SN associated with GRB060218,\nit is either rapidly evolving or it exploded days before the GRB.\n\nWe acknowledge the assistance of the ESO-Paranal staff.\n\n\nThis message may be cited.\"",
