Licandro (ING-IAC)\n\non behalf of a larger collaboration report:\n\nWe have observed the field of the GRB 060930 detected by INTEGRAL \n(Gotz et al., GCN 5665) with the 3.5m Telescopio Nazionale Galileo \n(+NICS) at La Palma in the JHK bands on 30 Sep 2006 (from 20:30 to \n20:51 UT) and revisited the field in H band on 1 Oct 2006 (from \n20:37 to 20:51 UT; i.e. 11.5 hr and 35.5 hr respectively after the \nonset of the gamma-ray event).\n\nThe NICS frames cover the central 80% of the INTEGRAL/IBIS error \nbox (2.5' radius). We detect a variable, stationary object at the \nfollowing coordinates (J2000):\n\nRA = 20:18:11.51, Dec = -23:37:19.6\n\nwith an astrometric error of 0.5\".\n\nIn the first epoch the source is detected in all 3 bands and has \nan H band magnitude of ~18.2. In the second H band epoch it has \nfaded by about 1 magnitude. This would imply a decay index of \nalpha -0.9 +/- 0.2 .\n\nFor this object we obtain (Js-K)=1.10+/-0.22, consistent with the\nnear-IR colour expected for a GRB afterglow (Gorosabel et al. 2002, \nA&A, 384, 11).\n\nA finding chart is available at:\n\nhttp://www.iaa.es/~deugarte/GRBs/060930/grb060930.gif\n\nThis message is quotable.",
