We observed the field of GRB 261110A triggered by SVOM/ECLAIRs (sb26111002, Wang et al., GCN 46215) using the 2.16m telescope located at Xinglong observatory, China, equipped with the BFOSC camera. We obtained 4*60s frames in R-band, starting at 12:12:11 UT on 2026-11-10, about 22.18 min after the trigger.

We found a candidate at RA = 350.8530709 deg, Dec = 33.0630451 deg with R ~ 21.4 within the ECLAIRs error box (Wang et al., GCN 46215). We notice there is a faint catalogued source in the Legacy Survey at this position with the brightness: g=24.07, r=23.61, z=23.06.

We thank the staff at Xinglong observatory for their excellent support.
