Sakamoto (AGU)\n\nWe observed the field of INTEGRAL Weak#8611 with the 14-inch\nAGU Robotic Optical Monitor for Astrophysical object - Narrow (AROMA-N)\nlocated at the Sagamihara campus of Aoyama Gakuin University.\n\n60 images of 60 sec exposures were taken in the R filter starting from\nNovember 13 16:59:58 (UT) about 189 seconds after the trigger and stopped\non November 13 18:15:10 (UT).  We do not detect the optical afterglow\nboth in the individual images and the stacked image.  The estimated\nfive sigma upper limit of the combined image (total exposure of 3600 sec)\nis ~17.9 mag using the USNO-B1 catalog.",
