Antonelli (INAF/OABr), report \non behalf of the MISTICI collaboration:\n\nWe observed the field of GRB 060116 (Campana et al., GCN 4519; Barthelmy \net al., GCN 4531) with the ESO-VLT UT2 equipped with FORS 1. Observations \nwere carried out in the R and I filters, starting on Jan 17.069 UT (17 h \nafter the burst).\n\nThe object reported by Kocevski, Bloom & McGrath (GCN 4528) is not \ndetected in our images down to a limiting magnitude I > 24.5 and R > 24.9 \n(3 sigma, calibrated against the USNO-B1 catalog).\n\nOur non detection indicates that the candidate object by Kocevski et al. \n(GCN 4528) is very likely the J-band afterglow of GRB 060116, which faded \nsignificantly between the two observations.\n\nWe further note a faint, red object inside the XRT error box (Campana et \nal., GCN 4522, 4529), at the coordinates (0.3\" arcsec error):\n\n   alpha(J2000) = 05:38:46.170;\n   delta(J2000) = -05:26:15.08.\n\nThis is 2.5\" away of the afterglow position (Kocevski et al., GCN 4528).\n\nA finding chart in the I filter is posted at the following URL:\n   http://www.merate.mi.astro.it/~davanzo/GRB/grb060116_find_I.jpeg\n\nThis message can be cited.\n\n[GCN OPS NOTE(18jan06): Per author's request, the affiliation was added to\nthe Malesani author.]",
