(LATT-OMP) report:\n\nWe solve technichal problems that prevent to\nacces to the first trailed image of GRB 061218\nobtained with TAROT located at the European Southern\nObservatory, La Silla observatory, Chile.\n\nThe observations started 61s after the GRB trigger\n(4s after the notice). The trailed image allows to\nfollow continuously variable sources during the 60s\nintegration time (see technichal description in\nKlotz et al., 2006, A&A 451, L39). We analyzed\nthe GRB error box provided by Sato et al. GCN\nCirc. 5940. No variable object is detected.\nTo summarize:\n\nt0+ 61.0s to t0+121.0s : R > 15.8\nt0+126.5s to t0+156.5s : R > 17.4 (CGNC 5943)\nt0+162.3s to t0+192.3s : R > 17.4 (CGNC 5943)\nt0+126.5s to t0+510.6s : R > 18.0 (CGNC 5943)\n\nMagnitudes were estimated with the nearby USNO-B1 stars\nand are not corrected for galactic dust extinction.\n\nThis message may be cited.",
