Zhao report on behalf of SVOM follow-up team:\n \nWe observed the field of GRB 261113A triggered by SVOM/ECLAIRs (sb26111302, Saccardi et al., GCN 46244) using the 2.16m telescope located at Xinglong observatory, China, equipped with the BFOSC camera. We obtained 6*60s frames in R-band, starting at 15:07:13 UT on 2026-11-13, about 36 min after the trigger.\n \nThe optical counterpart (Lin et al., GCN 46247; Lei et al., GCN 46248; Li et al., GCN 46249; Yin et al., GCN 46250) was well detected in our R-band image.\nWe measure a magnitude of R ~ 18.9 for the optical afterglow.\n\nWe thank the staff at Xinglong observatory for their excellent support.\n"
