MASTER-Kislovodsk robotic telescope  (Global MASTER-Net: 
http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, 
vol. 2010, 30L)  located in Russia (Lomonosov MSU, Kislovodsk Solar 
Station of Pulkovo observatory) started inspect of the LIGO/Virgo S191110x 
errorbox  561 sec after trigger time at 2019-11-10 18:18:03 UT, with upper 
limit up to  15.2 mag. The observations began at zenith distance = 87 deg. 
The sun  altitude  is -48.0 deg.

The galactic latitude b = -0 deg., longitude l = 206 deg.
