We observed the field of GRB 261011A detected by SVOM (Huang et al., GCN 45895) and Swift (Cenko et al., GCN 45896) using the 0.7-m telescope of the Thai Robotic Telescope network (TRT). A series of Sloan r-band frames were obtained.
The optical afterglow is detected at the Swift/UVOT position (Cenko et al., GCN 45896) with r ~ 19.1 at a median time of 37.6 mins after the Swift trigger.
Observations are ongoing.
