Zhou (NAOC) report:\n\nWe continued to observe the field of GRB 200613A (Fermi GBM team, GCN \n27926; Bissaldi 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 12:43:45 UT on 2020-06-15, 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; \nZhu et al., GCN 27943) is still clearly detected in our stacked image, \nwith R = 20.0 +/- 0.1 mag (at Tmid-T0 = 2.311 days post-burst), \ncalibrated with nearby Pan-STARRS1.\n\nFurther observations are planned.",
