TITLE: GCN CIRCULAR NUMBER: 15817 SUBJECT: GRB 140211A: MITSuME Okayama upper limits DATE: 14/02/11 14:40:40 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 and OISTER collaboration: We observed the field of GRB 140211A (Cummings et al., GCNC 15816) 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 2014-02-11 12:24:38 UT (~96 sec after the burst). We did not find any new point source within the BAT error circle (Cummings et al., GCNC 15816) in all the three bands. Three sigma upper limits of the OT are listed below. We used SDSS DR7 catalog for flux calibration. #T0+[day] MID-UT T-EXP[sec] g' Rc Ic ----------------------------------------------------- 0.00544 12:30:52 600.0 >18.2 >18.1 >17.4 ----------------------------------------------------- T0+ : Elapsed time after the burst [day] T-EXP: Total Exposure time [sec]
