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 S190910h errorbox  9379 sec after trigger time at 2019-09-10 11:06:17 UT, with upper limit up to  18.5 mag. Observations started at twilight.  The observations began at zenit distance = 58 deg. The sun  altitude  is -11.4 deg. 

The galactic latitude b = -60 deg., longitude l = 98 deg.
