Park (SKKU) and M. \nD.\nCaballero-Garcia (ASU-CAS, CZ) on behalf of a larger collaboration, \nreport:\n\nThe 60cm BOOTES-5/JGT robotic telescope at Observatorio Astronomico\nNacional in San Pedro Martir (Mexico) automatically responded in 95 s\nto the Swift trigger of GRB 181213A Evans et al., GCNC 23525).\nThe first image (10s exposure, g-band) was obtained at 12:59:13.72 UT.\nWithin the Swift/BAT error box, we identify an optical source at \ncoordinates\nRA = 16 33 04.75 Dec = +78 29 48.3 (J2000) of about 15.6 mag, which is \nfading\nin brightness in the late time images. Therefore we propose this source \nto be\nthe optical afterglow to GRB 181213A. Spectroscopic bbservations are \nencouraged.\n\nWe thank the staff at Observatorio Astronomico Nacional in San Pedro\nMartir for its excellent support.",
