TITLE: GCN CIRCULAR NUMBER: 15911 SUBJECT: GRB 140302A: MITSuME Okayama upper limits DATE: 14/03/03 01:15:14 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 140302A (Pagani et al., GCNC 15901) 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 2014-03-02 19:19:00 UT (~11.1 h after the burst). We could not detect the previously reported afterglow (Elliot et al., GCNC 15903) 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 ----------------------------------------------------- 0.48800 19:55:41 2400.0 >19.6 >19.4 >18.7 ----------------------------------------------------- T0+ : Elapsed time after the burst [day] T-EXP: Total Exposure time [sec]
