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 S200208q errorbox  9684 sec after trigger time at 2020-02-08 15:42:41 UT, with upper limit up to  16.7 mag. The observations began at zenith distance = 48 deg. The sun  altitude  is -49.0 deg. 

The galactic latitude b = 10 deg., longitude l = 263 deg.


Real time updated cover map and OT discovered available here:
