Yoshida (AGU)\n\nWe observed the field of GRB 160816A detected by Fermi (Racusin et al.,\nGCN Circ. 19802) with the iTelescope.Net (http://www.itelescope.net) T7\n(17\" Plane Wave) telescope located at the AstroCamp Observatory (Nerpio, Spain).\n15 images of 60 sec exposures were taken in the R filter starting from\nAugust 16 22:50:57 (UT) about 5.9 hours after the trigger and stopped on\nAugust 16 23:26:36 (UT).  We do not detect the optical afterglow both in the\nindividual images and the stacked image at the X-ray afterglow position\n(Kennea et al., GCN Circ. 19806).  The estimated five sigma upper limit\nof the combined image (total exposure of 900 sec) is ~18.3 using the\nUSNO-B1 catalog.",
