GCN 19580) with the 2-m \nLCOGT Faulkes Telescope North in Hawaii on July 01 from 11:12 UT to \n12:46 UT with the SDSS-r filter for a total exposure of 1500 s. We \nclearly detect the optical afterglow (Troja et al. GCN 19588; Oates et \nal. GCN 19589; Kuroda et al. GCN 19599; Xu et al. GCN 19600; D'Elia et \nal. GCN 19601; Karpov et al.
