GCN Circular 15073
K. Varela (MPE Garching), M. Tanga (MPE Garching), P. Afonso (American River College) and J. Greiner (MPE Garching) report on behalf of the GROND team: We observed a second epoch of the field of GRB 130803A (Swift trigger 565263; Page et al., GCN 15059) simultaneously in g'r'i'z'JHKs with GROND (Greiner et al.2008, PASP 120, 405) mounted at the 2.2m MPG/ESO telescope at La Silla Observatory (Chile). Observations started at 23:34 UT on August 5, about 61.7 hours after the trigger at a mean seeing of 1.5 arcsec and a mean airmass of 1.3. We confirm the detection of the source inside the enhanced 1.4'' XRT error circle (Swift webpage) reported in a previous GCN (Varela et al., GCN15066), and measure consistent magnitudes as compared to the first epoch (the g'-band magnitude contained an error and should read g' = 24.6 +/- 0.4). Thus, we consider this source as the potential host of GRB 130803A.
