Kiran (IIA, Bengaluru)\n\nWe observed the field of GRB 200613A (Fermi GBM team, GCN #27926; \nBissaldi et al., GCN #27930; Ohno et al., GCN #27931; Evans, GCN #27932) \nwith the Himalayan Faint Object Spectrograph and Camera (HFOSC) mounted \non the 2-m Himalayan Chandra Telescope located at IAO, Hanle, India. \nObservations started on 2020-06-19 at 15:20:43 UT and we obtained 3 \nframes, each of 300 sec in the Bessell R-band filter under moderate sky \nconditions.\n\nThe afterglow (Kann et al., GCN #27935; Pozanenko et al., GCN #27937; \nZhu et al., GCN #27943; Marshall, GCN #27944; Liu et al., GCN #27949; \nBelkin et al., GCN #27958; GCN #27978; GCN #27983; Fu et al., GCN \n#27971; Moskvitin et al., GCN #27982; Izzo, GCN #27998) is clearly \nvisible in the stacked image. We measure a preliminary magnitude of R = \n20.59 +/- 0.26 mag calibrated against the USNO-A2.0 catalogue stars. The \nhost contamination has not been removed in the analysis.\n\nWe thank the observing staff at IAO and CREST for helping with the \nobservations.",
