TITLE: GCN CIRCULAR NUMBER: 14963 SUBJECT: GRB 130701A: MITSuME Akeno Optical observation DATE: 13/07/02 11:43:41 GMT FROM: Taketoshi Yoshii at Tokyo Tech T. Yoshii, K. Ito, Y. Saito, Y. Yano, R. Usui, Y. Tachibana, S. Kurita, Y. Yatsu, and N. Kawai (Tokyo Tech) report on behalf of the MITSuME collaboration: We observed the field of GRB 130701A (N. P. M. Kuin et al., GCNC 14953) with the optical three color (g, Rc, and Ic) CCD cameras attached to the MITSuME 50 cm telescope of Akeno Observatory, Yamanashi, Japan. The observation started on 2013-07-01 14:33:09 UT ( ~10.3 h after the burst). And we could not find any new point source within the XRT error circle (N. P. M. Kuin et al., GCNC 14953) in all the three bands. The results of photometry (3 sigma upper limits) are listed below. We used GSC2.3 catalog for flux calibration. band T0+[hour] MID-UT T-EXP[sec] magnitude -------------------------------------------------------------------------------------------- g' ~13.0 17:19:49 1680 >19.2 Rc ~13.1 17:24:36 2880 >18.9 Ic ~13.0 17:17:28 1320 >18.0 -------------------------------------------------------------------------------------------- T0+ : Elapsed time after the burst [hour] T-EXP: Total Exposure time [sec]
