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
