Querel (NIWA), on behalf of a \nlarger collaboration, report:\n\nThe 60cm BOOTES-3/YA robotic telescope at NIWA Lauder in Otago (New \nZealand) responded to the Swift trigger of GRB 200612A (Sonbas et al. \nGCNC 27915). The first image (clear filter) was obtained starting at \n09:51:32 UT(~ 5.2 hr after trigger). In the co-added image (20 exposures \n60s each), no source is found at the position reported by Swift/XRT \n(Sonbas et al. GCNC 27915) and MASTER-Net (Lipunov et al. GCNC 27917) \ndown to 20.3 mag.\n\nWe thank the staff at NIWA for its excellent support.",
