MASTER-Tunka robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Applied Physics Institute, Irkutsk State University) started inspect of the LIGO/Virgo S200116ah errorbox 85 sec after notice time and 344 sec after trigger time at 2020-01-16 12:02:26 UT, with upper limit up to 17.3 mag. The observations began at zenith distance = 56 deg. The sun altitude is -23.3 deg.
MASTER-Amur robotic telescope located in Russia (Blagoveshchensk State Pedagogical University) started inspect of the LIGO/Virgo S200116ah errorbox 127 sec after notice time and 385 sec after trigger time at 2020-01-16 12:03:07 UT, with upper limit up to 17.4 mag. The observations began at zenith distance = 46 deg. The sun altitude is -38.7 deg.
The galactic latitude b = 16 deg., longitude l = 16 deg.
