(IAA-CSIC), C. Perez del Pulgar, A. Castellon, I. Carrasco (Univ. de 
Malaga), R. Fernandez-Munoz (IHSM/UMA-CSIC), M.D. Caballero-Garcia and 
M. Jelinek (ASU-CAS), on behalf of a larger collaboration, report:

The 60cm BOOTES-2/TELMA robotic telescope at IHSM La Mayora (UMA-CSIC) 
in Algarrobo Costa (Malaga, Spain) followed up GRB 181231A (Veres et al 
GCNC 23598). Nine images (60s exposure, unfiltered) were obtained with 
the COLORES imager spectrograph starting at 05:35:26 UT (~26.1 hr after 
trigger) in order to cover the entire Fermi/LAT error box (Dirirsa et 
al. GCNC 23597). No new optical sources were detected down to 18 mag.
