Szokoly (Eoetvoes Univ., Budapest) report on \nbehalf of the GROND team:\n\nWe observed the field of GRB 081105 (Swift trigger #333811; Cummings et al., \nGCN #8484) simultaneously in g'r'i'z'JHK with GROND (Greiner et al. 2008, \nPASP 120, 405) mounted at the 2.2 m ESO/MPI telescope at La Silla Observatory \n(Chile).\n\nObservations started at 02:01 UT on November 6th, 2008, 12.6 hr after the GRB \ntrigger with 23.0 min of total exposures in g'r'i'z' and 24.0 min in JHK. \nThey were performed at an average seeing of 1.4\" and at an average airmass of \n1.2.\n\nAs Ugarte Postigo et al. (GCN #8489), we do not detect any object within the \n4.8'' Swift-XRT error circle reported by Beardmore et al. (GCN #8487) down to \nthe following upper limits (all in AB system) of:\n\ng' > 23.3 mag,\nr' > 23.2 mag,\ni' > 22.5 mag,\nz' > 22.3 mag,\nJ > 21.6 mag,\nH > 21.0 mag and\nK > 20.0 mag.\n\nThese upper limits are derived based on calibrating the images against the \nGROND zeropoints as well as 2MASS field stars.",
