Pankov (IKI) report on behalf of GRB follow-up team\n\nWe observed the field of the GRB 260808B discovered by the SVOM\n(Bouchet et al., GCN 45316; Brunet et al., GCN 45333), also detected\nby EP-FXT (Wang et al., GCN 45322) with the Zeiss-1000, SAO RAS 1-m\ntelescope + CCD photometer. The observations were carried out on August 9,\n00:11:49--00:38:47 UT. We obtained 5 x 300 sec images in Rc band.\n\nThe OT (Turpin et al., GCNs 45317; 45318; Li et al.
