Yoshida (AGU) \n\nWe observed the field of GRB 151118A detected by Swift (trigger #664078; \nAmaral-Rogers et al., GCN Circ. 18611) with the iTelescope.Net (http://www.itelescope.net) \nT7 (17\" Plane Wave) telescope located at the AstroCamp Observatory (Nerpio, Spain).  \n20 images of 60 sec exposures were taken in the R filter starting from November 18 03:45:22 (UT) \nabout 38.8 minutes after the trigger and stopped on November 18 04:23:04 (UT).  \nWe do not detect the optical afterglow both in the individual images and the stacked image \nat the enhanced X-ray afterglow position (Evans et al., GCN Circ. 18614).  The estimated \nfive sigma upper limit of the combined image (total exposure of 1200 sec) is ~18.3 using \nthe USNO-B1 catalog.",
