Fynbo (DARK/NBI)\nreport on behalf of the X-shooter GRB collaboration:\n\nWe continued with the analysis of X-shooter's spectrum\n(Groot et al. GCN 10441) obtained for the afterglow of\nGRB 100219A (Rowlinson et al. GCN 10430). Additionally to\nthe strong Ly-alpha absorption reported in the previous GCN\nand the SiII and SiII* absorptions suggested by Cenko et al.\n(GCN 10443) we detect several other absorption features,\nincluding SII, OI, OI*, CII, CII*, SiIV, CIV, FeII, AlII and\nAlIII at a redshift of 4.6667 +/- 0.0005. We also detect an\nintervening system at z = 2.1810 +/- 0.0005 through the\nidentification of FeII, MgII and MgI. A second intervening\nsystem might be present at z = 1.7980 +/- 0.0005 identified\nby faint MgII and MgI absorptions. Further analysis is ongoing.",
