Greiner (all MPE Garching),\nreport on behalf of the GROND team:\n\nGROND observed the field of the INTEGRAL GRB 110206 (Mereghetti et al.,\nGCN# 11654) starting at 00:33 UT on 2011-02-07, which is 6.42 hours\nafter the trigger. In total, 1.7 hours of imaging was obtained\nsimultaneously in g'r'i'z'JHK. Within the enhanced XRT error circle\n(Evans, GCN #11657), we detect a single point source at\n\nRA (J2000): 06:09:20.04\nDecl (J2000): -58:48:24.9\n\nwith typical uncertainties of 0.5\" in each coordinate. These coordinates\nare consistent with the source detected by UVOT (Hoversten & Evans, GCN#\n11662).\nAt a midtime of 6.7 hours after the trigger we measure a preliminary AB\nmagnitude of r' = 21.2 +/- 0.1 based on the GROND zeropoint.\nThe source is detected in all GROND filters, which implies a redshift\nconstraint of z < 4.\n\nWithin the observational errors, no variability is evident in the\ntimeframe of the GROND observations, and hence we cannot claim the\nassociation of the source with GRB 110206A at the current stage.",
