Szokoly (Eoetvoes Univ., Budapest \nand MPE Garching) report on behalf of the GROND team:\n\nWe observed the field of GRB 080613A (INTEGRAL trigger 5288; Gotz et al., GCN \n#7871) simultaneously in g'r'i'z'JHK with GROND (Greiner et al. 2008, PASP \n120, 405) mounted at the 2.2m ESO/MPI telescope at La Silla Observatory \n(Chile).\n\nObservations started at 00:25 UT on June 14th, 2008, 14.8 hrs after the GRB \ntrigger with 25 mins of effective exposures in g'r'i'z' and 20 mins in JHK.\n\nWe do not detect any object at the position reported by Guidorzi et al., GCN \n#7872) to the following 3-sigma upper limits:\n\ng' > 24.2,\nr' > 23.9,\ni' > 23.5,\nz' > 23.4,\nJ > 22.3 and\nH > 21.3.\n\nGiven upper limits are calibrated against SDSS as well as 2MASS field stars.\n\nThis indicates a clear fading of the source. We therefore confirm this to be \nthe afterglow of GRB 080613A.",
