Observations \nwere carried out in the Johnson R (9x300 s) and SDSS z (6x300 s) filters \nunder moderate weather conditions (1.5\" seeing).\n\nNo objects are detected in either bands within the refined X-ray \nposition (Goad et al., GCN 17009), down to limiting magnitudes of R = \n22.5 (Vega) and z = 21.5 (AB), with mean times 7.93 and 8.48 hr after \nthe GRB (calibration against USNO B1 and SDSS, respectively).",
