MASTER-Tunka robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Applied Physics Institute, Irkutsk State University) started inspect of the LIGO/Virgo S200129m errorbox  15067 sec after trigger time at 2020-01-29 11:06:05 UT, with upper limit up to  16.4 mag. Observations started at twilight.  The observations began at zenith distance = 74 deg. The sun  altitude  is -11.8 deg. 

The galactic latitude b = -29 deg., longitude l = 56 deg.
