Greiner (MPE Garching) report on behalf of the\nGROND team:\n\nWe observed a second epoch of the field of GRB 130803A (Swift trigger\n565263; Page et al., GCN 15059) simultaneously in g'r'i'z'JHKs with GROND\n(Greiner et al.2008, PASP 120, 405) mounted at the 2.2m MPG/ESO telescope\nat La Silla Observatory (Chile).\n\nObservations started at 23:34 UT on August 5, about 61.7 hours after\nthe trigger at a mean seeing of 1.5 arcsec and a mean airmass of 1.3. We\nconfirm the detection of the source inside the enhanced 1.4'' XRT error\ncircle (Swift webpage) reported in a previous GCN (Varela et al.,\nGCN15066),\nand measure consistent magnitudes as compared to the first epoch\n(the g'-band magnitude contained an error and should read g' = 24.6 +/- 0.4).\nThus, we consider this source as the potential host of GRB 130803A.",
