Malaga), S. Guziy (Nikolaev Astronomical Observatory) and D. Xiong, Y.
Fan, X. Zhao, J. Bai, C. Wang, Y. Xin (Yunnan Nacional Astronomical
Observatory) on behalf of a larger collaboration, report:
Following the detection of GRB 190106A by Swift (Sonbas et al. GCNC
23615), the 0.6m BOOTES-4/MET robotic telescope at Lijiang Astronomical
Observatory (China) triggered alert at 15:12:56 UT (~1.6 hr after
trigger). The reported optical afterglow (Yurkov et al. GCNC 23614,
Lipunov et al. GCNC 23616, Itoh et al. GCNC 23617, Mao et al. GCNC
23618, Reva et al. GCNC 23620 and Xin et al. 23622) is still clearly
detected within the refined XRT position (Goad et al. GCNC 23619). A
preliminary photometry yields a magnitude of 19.4 +/- 0.1 (g-band).
Observations are ongoing.
