A set of of 48x60s clear (roughly R)\n\nfilter images were obtained. Preliminary analysis do not reveal any\n\nnew optical counterpart candidate within the X-ray afterglow error\n\ncircles (Page et al., GCN 37334), neither in single image, nor in\n\nthe co-add images. We estimate the limiting magnitude of our coadd\n\nimage to be ~20.5 mag.\n",
