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