Perez del Pulgar (UMA) and I. M. Carrasco-Garcia (SMA) and I. H. Park (SKKU), on behalf of a larger collaboration, report:
Following the detection of GRB 231129A by Swift (Gropp et al. GCNC 35208), INTEGRAL (Mereghetti et al. GCNC 35209) and GECAM-C (Zhang et al. GCNC 35210), the BOOTES-5/JGT 0.6m robotic telescope at Observatorio Astronomico Nacional in San Pedro Martir (Mexico) automatically observed the GRB location starting on Nov. 29, 05:07 UT (~ 61 s after trigger). No new optical source is detected on the co-added image (15 x 10 s, clear filter) within the Swift/XRT error region (Goad et al. GCNC 35220) down to 19.9 mag, which is consistent with reports from MASTER (Lipunov et al. GCNC 35212), Mondy (Belkin et al. GCNC 35232), UVOT (Breeveld et al. GCNC 35233) and JinShan (Liu et al. GCNC 35237).
We thank the staff at Observatorio Astronomico Nacional in San Pedro Martir for their excellent support.
