We continued observations of GRB 200613A (Fermi GBM team, GCN 27926;
Bissaldi et al., GCN 27930; Ohno et al., GCN 27931; Yamaoka Ohno et al.,
GCN 27964) with Kitab-ISON RC-36 telescope in Clear filter. The optical
afterglow (e.g., Kann et al., GCN 27935; Pozanenko et al., GCN 27937;
Izzo et al., GCN 27939; Zhu et al., GCN 27943) is detected in a stacked
image. Preliminary photometry of the afterglow is following
