The 60cm BOOTES-5/JGT robotic telescope at Observatorio Astronomico
Nacional in San Pedro Martir (Mexico) automatically responded in 95 s
to the Swift trigger of GRB 181213A Evans et al., GCNC 23525).
The first image (10s exposure, g-band) was obtained at 12:59:13.72 UT.
Within the Swift/BAT error box, we identify an optical source at 
RA = 16 33 04.75 Dec = +78 29 48.3 (J2000) of about 15.6 mag, which is 
in brightness in the late time images. Therefore we propose this source 
to be
the optical afterglow to GRB 181213A. Spectroscopic bbservations are 

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