TITLE: GCN CIRCULAR NUMBER: 12511 SUBJECT: GRB111029A: MITSuME Ishigakijima Optical Upper Limits DATE: 11/10/30 13:25:56 GMT FROM: Daisuke Kuroda at OAO/NAOJ D. Kuroda (OAO, NAOJ), H. Hanayama, T. Miyaji, J. Watanabe (IAO, NAOJ), K. Yanagisawa (OAO, NAOJ), S.Nagayama (NAOJ), M. Yoshida (Hiroshima), K. Ohta (Kyoto) and N. Kawai(Tokyo Tech) report on behalf of the MITSuME collaboration: We observed the field of GRB 111029A (Troja et al., GCNC 12498) with the optical three color (g', Rc and Ic) CCD camera attached to the Murikabushi 1m telescope of Ishigakijima Astronomical Observatory. The observation started on 2011-10-29 15:49:45 UT, (~6.1 h after the burst). We did not find any new point source within the enhanced XRT error circle (Evans et al., GCNC 12502) in all the three bands. Photometric results of the OT are listed below. We used GSC2.3 catalog for flux calibration. #T0+[day] MID-UT T-EXP[sec] g' Rc Ic ----------------------------------------------------- 0.30785 17:07:59 13140.0 >22.6 >22.0 >20.7 ----------------------------------------------------- T0+ : Elapsed time after the burst [day] T-EXP: Total Exposure time [sec]
