Following the detection of GRB 221028A by Swift (Lien et al. GCNC 32874), the 0.6m BOOTES-4/MET robotic telescope at Lijiang Astronomical Observatory (China) automatically responded to this burst starting on Oct. 28 at 13:24:22 UT (~8 min after trigger). No new source is detected within the XRT error region (Lien et al. GCNC 32874) in the co-added image (33 x 10 s, clear filter) down to 19.9 mag, which is consistent with the non-detection reported by GIT (Kumar et al., GCNC 32876).
We thank the staff at Lijiang observatory for their excellent support.
