Observations began at 06:02 UT on June 7th,\napproximately 11 hours after the burst, and were obtained in the r, i and \nz-bands, with a total of 900s exposure in each band. Within the refined \nXRT error circle (Evans et al. GCN 10827) we find a faint, and apparently\nextended source, with r~25 (using archival zero point), which is barely \nvisible in our i and z-band observations, suggesting a relatively blue \ncolour. Although it is plausible that this object contains some \ncontribution from a faint afterglow, the extended source is apparently \ndominating, and we suggest that this is the host of GRB 100606A.\n\nThe faint afterglow (r>25), combined with the apparently high X-ray\ncolumn density (Littlejohns et al. GCN 10829) is consistent with\nGRB 100606A as a highly extinguished burst.\n\nWe thank the staff of Gemini South, especially Peter Pessev, for\nthe help in acquiring these data.",
