and A. J. Castro-Tirado (IAA-CSIC), D. Hiriart and W. H. Lee (UNAM), S. 
Jeong and I. H. Park (SKKU) and M. D. Caballero-Garcia (ASU-CAS, CZ) on 
behalf of a larger collaboration, report:

The 60cm BOOTES-5/JGT robotic telescope at Observatorio Astronomico 
Nacional in San Pedro Martir (Mexico) observed GRB 191213A ( Cenko et 
al., GCNC 26398 ) starting at 13:16 UT (~9.17 hr after trigger) at high 
airmass. Within the refined Swift/BAT error position ( Lien et al., GCNC 
26418 ), no optical afterglow is found down to 18.6 mag in the clear 
filter on the co-added 15 images (60s each).

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