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 S241109bn errorbox 16 sec after trigger time at 2024-11-09 11:59:40 UT, with upper limit up to 19.9 mag. The observations began at zenith distance = 60 deg. The sun altitude is -24.0 deg.
The galactic latitude b = -22 deg., longitude l = 314 deg.
Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/ligo_1.php?id=23757
We obtain a following upper limits.
