Zhou (NAOC) report:\n\nWe observed the field of GRB 200613A (Fermi GBM team, GCN 27926; \nBissaldi et al., GCN 27930; Ohno et al., GCN 27931) using the \nXinglong-2.16m telescope equipped with the BFOSC camera. Observations \nwere carried out starting at 12:44:18 UT on 2020-06-14, and 5x300s \nR-band frames were obtained.\n\nThe previously reported afterglow (e.g., Kann et al., GCN 27935; Kennea \net al., GCN 27936; Pozanenko et al., GCN 27937; Izzo et al., GCN 27939) \nis clearly detected in our stacked image, with R = 19.45 +/- 0.05 mag \n(at Tmid-T0 = 1.266 days post-burst), calibrated with nearby Pan-STARRS1.",
