D'Elia et\nal., GCN #16882) simultaneously in g'r'i'z'JHK with GROND (Greiner et al.\n2008, PASP 120, 405) mounted at the 2.2 m MPG telescope at ESO La Silla\nObservatory (Chile).\n\nWe detect a source consistant with the position reported by Perley et al.\n(GCN #16884). From coadded observations, starting on October 05 and\nspanning from 23:50 to 00:04 UT, we report the following preliminary\nmagnitudes and upper limits (AB magnitude system) of:\n\ng' > 21.6,\nr' = 21.7 +/- 0.2,\ni' = 21.7 +/- 0.2,\nz' = 21.2 +/- 0.2,\nJ  > 20.5,\nH  > 19.9, and\nK  > 18.2.\n\nGiven magnitudes and upper limits are calibrated against SDSS as well as\n2MASS field stars and are not corrected for the expected Galactic\nforeground extinction corresponding to a reddening of E_(B-V)=0.17 mag in\nthe direction of the burst (Schlegel et al. 1998).",
