TITLE: GCN CIRCULAR NUMBER: 7740 SUBJECT: GRB 080516, GROND observations DATE: 08/05/17 00:15:11 GMT FROM: Sylvio Klose at TLS Tautenburg R. Filgas (Tautenburg), A. Kupcu-Yoldas, J. Greiner (MPE Garching), A. Rossi, S. Klose (Tautenburg), A. Yoldas, T. Kruehler (MPE), and G. Szokoly (Eoetvoes Univ. Budapest and MPE) report on behalf of the GROND team: We observed the field of GRB 080516 (Holland et al. 2008, GCN 7733) simultaneously in g'r'i'z'JHK using the multi-channel imager GROND (Greiner et al. 2008, PASP 120, 405) mounted at the 2.2m MPI/ESO telescope on La Silla (Chile). Observations started at 00:25 UT, 8 min after the burst. At the border of the revised XRT error circle (Beardmore et al., GCN 7735) we detect in all bands a faint source at RA, DEC (J2000) = 08:02:33.96, -26:09:33.6 (+/- 0.5") with r'= 23.92 +/- 0.2 at ~1 hr after the burst, calibrated against NOMAD field stars. This source is very close to a brighter foreground point source and close to a very bright star (Cobb et al., GCN 7738). Note that due to visibility constraints observations could only be performed for two hours. Problems with the photometry did not allow us to report these results earlier.
