Wang, Y. Xin (Yunnan Nacional Astronomical Observatory), Ch. Cui (Beijing
National Astronomical Observatory) and A. J. Castro-Tirado (IAA-CSIC), on
behalf of a larger collaboration, report:

�Following the detection of GRB 121226A by Swift (Krimm et al. GCNC
14105), the 0.6m BOOTES-4/MET robotic telescope at the Lijiang
Astronomical Observatory (China) responded automatically to the trigger
alert at 19:10:21 UT, 9 s after the GCN reception (i.e. 36 s after the
onset of the event). After initial 0.5 s exposures, the first 19
unfiltered images (5 s exposure time each) starting 6 m 24 s postburst,
show no optical afterglow at the refined XRT position down to 19th mag
limiting magnitude (for the combined image). Observations are ongoing.�
