Berger (Harvard) report:\n\n\"We observed the location of the short-duration GRB 140516A (Bernardini et\nal., GCN 16285) with the Gemini Multi-Object Spectrograph (GMOS) mounted on\nthe Gemini-North 8-meter telescope at a mid-time of 2014 May 17.373 UT\n(12.38 hr post-burst). We obtained i-band observations for a total of\n1800-sec in 0.5\" seeing. We do not detect any optical source within the XRT\nposition (Osborne et al., GCN 16289). Calibrated to SDSS, we therefore\nplace a 3-sigma limit of i>26.1 AB mag on the optical afterglow of GRB\n140516A at 12.38 hr after the burst.\n\nWe thank Gemini observer Lucas Fuhrman for assistance with these\nobservations.\"",
