Zhu (HUST) report:\n\nWe observed the field of GRB 261113A detected by SVOM/ECLAIRs (GCN 46244) using the 100A and 100C telescopes of the JinShan project locate at Altay, Xinjiang, China. A series of Sloan r-band frames were obtained.\n\nAn uncatalogued and varying optical source is detected within the SVOM/ECLAIRs error circle at coordinates\n\nR.A. (J2000) = 23:05:16.96\nDec. (J2000) = +5:10:18.65\n\nwith an uncertainty of ~1 arcsec. The source has r = 19.14 +/- 0.05 mag at a median time of 0.5 hr post-trigger, calibrated with nearby PanSTARRS stars.\n\nWe thus think the source is the optical afterglow of GRB 261113A.",
