MASTER-Amur robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Blagoveshchensk State Pedagogical University) started inspect of the LIGO/Virgo S230611l errorbox 23783 sec after notice time and 24454 sec after trigger time at 2023-06-11 13:08:47 UT, with upper limit up to 16.3 mag. Observations started at twilight. The observations began at zenith distance = 67 deg. The sun altitude is -10.5 deg.
The galactic latitude b = 60 deg., longitude l = 105 deg.
