TITLE: GCN CIRCULAR NUMBER: 16405 SUBJECT: GRB 140614B: MITSuME Okayama upper limits DATE: 14/06/15 01:44:49 GMT FROM: Daisuke Kuroda at OAO/NAOJ D. Kuroda, K. Yanagisawa, Y. Shimizu, H. Toda (OAO, NAOJ), S. Nagayama (NAOJ), M. Yoshida (Hiroshima), K. Ohta (Kyoto) and N. Kawai(Tokyo Tech) report on behalf of MITSuME collaboration: We observed the field of GRB 160614B (Page et al., GCNC 16394) with the optical three color (g', Rc and Ic) CCD camera attached to the MITSuME 50cm telescope of Okayama Astrophysical Observatory. The observation started on 2014-06-14 16:44:18 (~10.1 h after the burst). We did not find any new point source within the enhanced XRT circle (Evans et al., GCNC 16395) in all the three bands. Three sigma upper limits of the OT are listed below. We used GSC 2.3 catalog for flux calibration. #T0+[day] MID-UT T-EXP[sec] g' Rc Ic ----------------------------------------------------- 0.46713 17:50:51 6060.0 >19.2 >19.3 >18.6 ----------------------------------------------------- T0+ : Elapsed time after the burst [day] T-EXP: Total Exposure time [sec]
