Querel (NIWA), on behalf of a \nlarger collaboration,\nreport:\n\nThe 60cm BOOTES-3/YA robotic telescope at NIWA Lauder in Otago (New \nZealand) automatically responded to the Swift trigger of GRB 181203A \n(Troja et al. GCNC 23493) ~0.51 h after the burst.  At the position of \nthe Swift/XRT enhanced X-ray position (Goad et al. GCNC 23494), no \noptical afterglow is detected down to 20.4 mag on a 360s co-added \nunfiltered image at 0.62 h (middle exposure) after trigger, in agreement \nwith the non-detection by Swift/UVOT (Marshall et al. GCNC 23505).\n\nWe thank the staff at NIWA for its excellent support.",
