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 S230529p errorbox 531 sec after notice time and 11954 sec after trigger time at 2023-05-29 13:46:58 UT, with upper limit up to 17.0 mag. Observations started at twilight. The observations began at zenith distance = 67 deg. The sun altitude is -15.0 deg.
The galactic latitude b = -15 deg., longitude l = 256 deg.
Real time updated cover map and OT discovered available here:
