Yoshida (AGU) \n\nWe observed the field of GRB 151127A detected by Swift (trigger #665268; \nD'Ai et al., GCN Circ. 18643) with the iTelescope.Net (http://www.itelescope.net) \nT30 (20\" Plane Wave) telescope located at the Siding Spring Observatory (New South \nWales, Australia).  20 images of 60 sec exposures were taken in the R filter \nstarting from November 27 09:47:56 (UT) about 39.1 minutes after the trigger \nand stopped on November 27 10:23:18 (UT).  We do not detect the optical afterglow \nboth in the individual images and the stacked image at the enhanced X-ray afterglow \nposition (Goad et al., GCN Circ. 18647).  The estimated five sigma upper limit of \nthe combined image (total exposure of 1200 sec) is ~18.2 using the USNO-B1 catalog.",
