Xin\n(Yunnan National Astronomical Observatory, China) on behalf of a larger\ncollaboration, report:\n\nFollowing the detection of GRB 141109B by Swift/BAT (Melandri et al., GCNC\n17038), the robotic 0.6m MET telescope at the BOOTES-4 station, in Lijiang\nAstronomical Observatory (China) responded to the event after the sunset,\nwith the first images being obtained about 3.5 h post-burst. Additional\nR-band images (6 x 300s) were taken at the 2.0m Terskol telescope in the\nNorthern Caucasus starting 11.3 hr post-burst. No optical source is\ndetected at the refined Swift/XRT position (Beardmore et al., GCNC 17045)\ndown to the DSS limit. Observations at longer wavelengths are encouraged.",
