GRB 170519A: MITSuME Akeno Optical Observation
Abstract
report on behalf of the MITSuME collaboration: We searched for the optical counterpart of GRB 170519A (T. N. Ukwatta et al., GCN Circular #21106) 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 2017-05-19 11:03:14 UT (21192 sec after the burst). We detected the optical counterpart (T. N. Ukwatta et al., GCN Circular #21106) in g', Rc and Ic band. The measured magnitudes were listed as follows. T0+[hour] MID-UT T-EXP[sec] g' Rc Ic ---------------------------------------------------------------------------- ~5.9 11:34:54 4278 (B19.14+/-0.15 18.48+/-0.11 18.13+/-0.13 ---------------------------------------------------------------------------- T0+ : Elapsed time after the burst T-EXP: Total Exposure time We used GSC2.3 catalog for flux calibration.
