report on behalf of IKI-GRB-FuN:
We observed the field of a Fermi short GRB 200826A (Fermi GBM team, GCN
28284; Kunzweileret al., GCN 28286; Manganal., GCN 28287) with
Kitab-ISON RC-36 telescope in Clear filter. In particular we cover a
whole region of IPN localization (Hurley et al., GCN 28291). The
optical afterglow ZTF20abwysqy/AT2020scz (Carracedo et al., GCN 28293;
Ahumada et al., GCN 28295) is not detected. Preliminary photometry of
the filed is following
