MASTER-Amur robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Blagoveshchensk State Pedagogical University) started inspect of the LIGO/Virgo S200112r errorbox  223 sec after trigger time at 2020-01-12 16:02:21 UT, with upper limit up to  17.6 mag. The observations began at zenith distance = 76 deg. The sun  altitude  is -61.3 deg. 

The galactic latitude b = -14 deg., longitude l = 35 deg.
