Kubanek (IP AS CR & IAA-CSIC), report on behalf of\na larger collaboration:\n\n\"We observed the field of GRB 120612A (Pagani et al., GCNC 13357), detected\nby Swift/BAT, with the 0.6m Yock-Allen robotic telescope (BOOTES-3) located\nin Blenheim, New Zealand. Unfiltered images were obtained starting\n05:58:29UT (3h53m after the burst, limited by sunset). The first 40 images,\neach of 60 seconds, were combined (with the last exposure ending at\n06:39:14 UT). This resulted in a limiting magnitude of 18.0 when calibrated\nwith the R1Mag value of USNO-B1.0 catalogue stars.\"\n\nThis message may be cited.",
