Belkin (IKI, HSE)  report on behalf of GRB IKI FuN:\n\nWe observed the  Swift GRB 231110A (D'Elia et al., GCN #34977) with Zeiss-2000  telescope of Terskol observatory starting on 2023-11-10 (UTC) 23:25:16. We do not detect any object within Source #2 of XRT probable afterglow (Beardmore et al., GCN 34986). This is cosnistent with non-detection in other observations (Lipunov et al., GCN 34978; Sun et al., GCN 34979; Sun et al., GCN 34985; Moskvitin et al., GCN 34987; Gompertz et al., GCN 34988).
