MASTER-Tavrida robotic telescope  (Global MASTER-Net: 
http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, 
vol. 2010, 30L)  located in Russia (Lomonosov MSU, SAI Crimea astronomical 
station) started inspect of the LIGO/Virgo S191110af errorbox  41 sec 
after trigger time at 2019-11-10 23:07:25 UT, with upper limit up to  16.5 
mag. The observations began at zenith distance = 78 deg. The sun  altitude 
is -55.8 deg.

MASTER-Kislovodsk robotic telescope  located in Russia (Lomonosov MSU, 
Kislovodsk Solar Station of Pulkovo observatory) started inspect of the 
LIGO/Virgo S191110af errorbox  240 sec after trigger time at 2019-11-10 
23:10:44 UT, with upper limit up to  16.9 mag. The observations began at 
zenith distance = 79 deg. The sun  altitude  is -51.3 deg.

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