MASTER-Kislovodsk robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) started inspect of the LIGO/Virgo S230608as errorbox 4 sec after notice time and 53 sec after trigger time at 2023-06-08 20:51:40 UT, with upper limit up to 17.6 mag. The observations began at zenith distance = 85 deg. The sun altitude is -24.0 deg.
The galactic latitude b = -1 deg., longitude l = 150 deg.
