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 S190808ae errorbox  0 sec after notice time and 471 sec after trigger time at 2019-08-08 22:29:12 UT, with upper limit up to  17.3 mag. The observations began at zenit distance = 59 deg. The sun  altitude  is -31.4 deg. 

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