GRB 170705A: MITSuME Akeno Optical Observation
Abstract
We searched for the optical counterpart of GRB 170705A (R. L. C. Starling et al., GCN Circular #21289) with the optical three color (g', Rc, and Ic) CCD cameras attached to the MITSuME 50cm telescope of Akeno Observatory, Yamanashi, Japan. The observation started on 2017-07-05 11:21:20.84 UT. We did not find any new point source within XRT circle in all three bands. We obtained following limits for the magnitudes. T0+[hour] MID-UT T-EXP[sec] g' Rc Ic ------------------------------------------------------------------------------------------------------- ~8.59 12:29:51 1320 >18.5 >17.9 >17.8 ------------------------------------------------------------------------------------------------------- T0+ : Elapsed time after the burst T-EXP: Total Exposure time We used GSC2.3 catalog for flux calibration.
