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/KAGRA S231102i errorbox 38402 sec after notice time and 38635 sec after trigger time at 2023-11-02 14:45:39 UT, with upper limit up to 16.5 mag. The observations began at zenith distance = 13 deg. The sun altitude is -45.9 deg.
The galactic latitude b = -10 deg., longitude l = 271 deg.
Real time updated cover map and OT discovered available here:
