TITLE: GCN CIRCULAR NUMBER: 11940 SUBJECT: GRB110414A: MITSuME Ishigakijima Optical upper limits DATE: 11/04/15 22:48:58 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 110414A (Starling et al., GCN 11931) 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 10:57:59 UT (~3.3 h after the burst). We did not find any new point source within the Enhanced XRT circle (Osborne et al., GCN 11934) in all the three bands. Three sigma upper limits of the OT are listed below. We used GSC2.3 catalog for flux calibration.
