Lee (UNAM), C. J. Perez del Pulgar (UMA), I. M. Carrasco-Garcia (SMA) and I. H. Park (SKKU), on behalf of a larger collaboration, report:

Following the detection of GRB 240730A by Swift (Cenko et al. GCNC 36976), the BOOTES-5/JGT 0.6m robotic telescope at Observatorio Astronomico Nacional in San Pedro Martir (Mexico) automatically observed the GRB location starting on Jul. 30, 07:53:50 UT (~ 104 s after trigger). No new optical source is detected on the co-added images (57 x 1 s, clear-filter) within the enhanced Swift/XRT error box (Evans et al. GCNC 36977) down to 18.7 mag.  which is consistent with reports from UVOT (Kuin et al., GCNC 36978), KAIT (Zheng et al., GCNC 36980) and MASTER (Lipunov et al. GCNC 36983).

We thank the staff at Observatorio Astronomico Nacional in San Pedro Martir for their excellent support.
