TITLE: GCN CIRCULAR NUMBER: 8627 SUBJECT: GRB 081204: GROND Observations DATE: 08/12/06 11:45:59 GMT FROM: Adria C. Updike at Clemson U A. Updike (Clemson University), C. Clemens, and J. Greiner (both MPE Garching) report on behalf of the GROND team: We observed the field of GRB 081204 (INTEGRAL trigger #5385; D. Gotz et al., GCN #8614) for two epochs simultaneously in g'r'i'z'JHK with GROND (Greiner et al. 2008, PASP 120, 405) mounted at the 2.2 m ESO/MPI telescope at La Silla Observatory (Chile). Observations began at 00:30 UT on Dec 5, 2008, 7.75 hr after the GRB trigger, and consisted of 2.4 hours of exposures. The second epoch began at 00:31 UT on Dec 6, 31.75 hr after the trigger, and consisted of 1.3 hours of exposures. Observations were performed under favorable sky conditions. We detect two sources within the refined 5.3'' Swift-XRT error circle reported by V. Mangano et al. (GCN #8620), at the astrometrically corrected positions: RA (J2000.0) 23h 19m 09.10s Dec (J2000.0) -60d 13' 29.7" and RA (J2000.0) 23h 19m 09.37s Dec (J2000.0) -60d 13' 31.2" The second candidate agrees with the position reported by Berger & Rest (GCN #8624). We detect no evidence of fading in either source between the two epochs. Therefore, we suggest that neither of the sources are the afterglow of GRB 081204. Our upper limits from the first epoch in g'r'i'z'JHK are as follows: g' > 24.2 r' > 24.3 i' > 23.6 z' > 22.9 J > 20.7 H > 19.4 K > 18.3 The given magnitudes are calibrated against GROND zeropoints as well as 2MASS field stars.
