MASTER-IAC robotic telescope  (Global MASTER-Net: 
http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, 
vol. 2010, 30L)  located in Spain (IAC Teide Observatory) started inspect 
of the LIGO/Virgo S191109d errorbox  863 sec after notice time and 1475 
sec after trigger time at 2019-11-09 01:31:52 UT, with upper limit up to 
19.8 mag. The observations began at zenith distance = 71 deg. The sun 
altitude  is -74.6 deg.
