TITLE: GCN CIRCULAR NUMBER: 19918 SUBJECT: GRB 160912A Liverpool Telescope optical afterglow DATE: 16/09/13 08:04:49 GMT FROM: Nial Tanvir at U.Leicester N. R. Tanvir (U. Leicester), A. J. Levan (U. Warwick), report on behalf of a larger collaboration: We observed the field of Swift GRB 160912A (Cannizzo et al. GCN 19912) with the 2m Liverpool Telescope on La Palma with the IO:O camera. Images were obtained in the r and i filters at two epochs, each exposure being 25 mins in total. Within the revised X-ray error circle (Beardmore et al. GCN 19915) we find a point source with the following provisional magnitudes and start times relative to the BAT trigger time: epoch1 dt=17053s i=22.10+/-0.15 epoch1 dt=18664s r=22.77+/-0.20 epoch2 dt=29285s i=22.57+/-0.17 epoch2 dt=30897s r=23.11+/-0.21 Given the evidence for fading, we conclude this is likely the optical afterglow of the GRB. The J2000 position of the source is 20:05:59.68 +57:33:54.9 to an accuracy of about 0.5".
