(UBAI) report on behalf of IKI-GRB-FuN:
We observed GRB 200716C (Fermi GBM team, GCN 28123; Ukwatta et al GCN
28124; Ohno et al., GCN 28130; Ursi et al., GCN 28133; Torii et al., GCN
28139; Xue et al., GCN 28145; Frederiks et al., GCN 28147) with RC-36
telescope of Kitab observatory starting July 17 (UT) 17:24:57. The
optical afterglow (Ukwatta et al., GCN 28124; Lipunov et al., GCN 28125;
Hu et al., GCN 28126; Kumar et al., GCN 28138; Gokuldass et al., GCN
28146; Jelinek et al., GCN 28149; Pozanenko et al., GCN 28151; Kann et
al., GCN 28152) is detected in a stacked image. Despite we do not
detect possible host galaxy (D���Avanzo et al., GCN 28132) the galaxy may
contaminate photometry result. Preliminary photometry of the afterglow
is following
