MASTER-OAFA robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Argentina (OAFA observatory of San Juan National University) started inspect of the LIGO/Virgo S230617aq errorbox 32815 sec after notice time and 32883 sec after trigger time at 2023-06-18 01:25:54 UT, with upper limit up to 19.5 mag. The observations began at zenith distance = 48 deg. The sun altitude is -47.5 deg.
The galactic latitude b = -15 deg., longitude l = 144 deg.
