GCN Circular 7586
T. Kruehler, A. Kupcu Yoldas, J.Greiner, C. Clemens, A. Yoldas (all MPE Garching) and G. Szokoly (Eoetvoes Univ., Budapest and MPE Garching) report on behalf of the GROND team: We observed the field of GRB 080411 detected by BAT (Marshall et al., GCN #7584) simultaneously in g'r'i'z'JHK with GROND mounted at the 2.2m ESO/MPI telescope at La Silla Observatory (Chile). Observations started in twilight at 23:15 UT on April 11th, 2008, 2h after the burst. We detect a new bright point source just at the edge of the XRT error circle (Marshall et al. GCN #7584) at RA (J2000.0) = 02:31:55.20 DEC (J2000.0) = -71:18:07.6 with an uncertainty of 0.8". The object is detected in all of the seven bands, implying a redshift smaller than 3.5. Preliminary photometry yields an r' band magnitudes of 16.5 calibrated against USNO field stars. The given magnitudes are not corrected for the Galactic foreground reddening of E(B-V)=0.03 mag (Schlegel et al., 1998).
