GCN Circular 4452
P. D'Avanzo (INAF/OABr), S. Piranomonte (INAF/OAR), D. Malesani (SISSA), G. Chincarini (Univ. Milano-Bicocca), L. Stella (INAF/OAR) and G. Tagliaferri (INAF/OABr), report on behalf of the MISTICI collaboration: We observed the field of GRB 060108 (Oates et al., GCN 4443; Sakamoto et al., GCN 4445) with the ESO-VLT UT1 equipped with the ISAAC camera, starting on Jan 9.307 UT (0.7 d after the GRB). Coaddition of ten 90 s exposures does not reveal any object inside the XRT error circle (Page et al., GCN 4444) down to a limiting magnitude J = 22.3 (3 sigma confidence level). This limit (see also Guidorzi et al., GCN 4447) implies a faint afterglow, as observed in other Swift GRBs. If this faintness is due to a Lyman dropout, the non detection in J implies a redshift z > 9. This message can be cited.
