TITLE: GCN CIRCULAR NUMBER: 15771 SUBJECT: GRB 140129A: MITSuME Okayama upper limits DATE: 14/01/30 00:13:58 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 140129A (Melandri et al., GCNC 15760) 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 2014-01-29 09:31:12 UT (~6.1 h after the burst). We could not detect the previously reported afterglow (Melandri et al., GCNC 15760; Perley and Cenko, GCNC 15761) in all the three bands. Three sigma upper limits of the OT are listed below. We used GSC2.3 catalog for flux calibration. #T0+[day] MID-UT T-EXP[sec] g' Rc Ic ----------------------------------------------------- 0.29723 10:32:00 4020.0 >19.6 >19.7 >18.9 ----------------------------------------------------- T0+ : Elapsed time after the burst [day]
