Yoshida (AGU) \n\nWe observed the field of GRB 151212A detected by MAXI (Nakahira et al., GCN Circ. 18685) \nwith the iTelescope.Net (http://www.itelescope.net) T18 (Plane Wave CDK) telescope located \nat the AstroCamp Observatory (Nerpio, Spain).  20 images of 60 sec exposures were taken \nin the Red filter starting from December 12 22:43:00 (UT) about 8.7 hours after the trigger \nand stopped on December 12 23:17:03 (UT).  We do not detect the optical afterglow both in the \nindividual images and the stacked image at the X-ray afterglow position \n(Roegiers et al., GCN Circ. 18687).  The estimated five sigma upper limit of the combined \nimage (total exposure of 1200 sec) is ~17.0 using the USNO-B1 catalog.",
