GRB 180514A: MITSuME Akeno optical upper limits
Abstract
We searched for the optical counterpart of GRB 180514A (LaPorte et al., GCN Circular #22723) 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 2018-05-14 13:39:12 UT. We did not find any point source at the position of the XRT error circle in all three bands. We obtained following limits for the magnitudes. T0+[min] MID-UT T-EXP[sec] g' Rc Ic ------------------------------------------------------------------------------------------------------- ~13.6 14:18:59 4,200 >18.7 >19.2 >18.1 ------------------------------------------------------------------------------------------------------- T0+ : Elapsed time after the burst T-EXP: Total Exposure time We used UCAC-4 catalog for flux calibration.
