TITLE: GCN CIRCULAR NUMBER: 28902 SUBJECT: INTEGRAL Weak#8811: AROMA-N Optical Observation DATE: 20/11/16 08:07:00 GMT FROM: Takanori Sakamoto at AGU K. Hasuda, M. Nakamura, T. Sakamoto (AGU) 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.
