S. Belkin (IKI), A. Pozanenko (IKI),�� V. Rumyantsev (CrAO),�� A. Volnova
(IKI), E. Mazaeva (IKI) report on behalf of larger GRB follow-up
collaboration:
We observed the�� GRB 200613A (Fermi GBM team, GCN 27926; Bissaldi et
al., GCN 27930; Ohno et al., GCN 27931; Yamaoka Ohno et al., GCN 27964)��
with ZTSH 2.6m telescope of CrAO observatory starting on 2020-06-20 (UT)
19:19:12.�� 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; Marshall, GCN 27944; Liu et al., GCN 27949; Belkin et al., GCN
27958) is detected in a stacked image. Preliminary photometry of the
afterglow is following
