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 S230616s errorbox 103 sec after notice time and 201 sec after trigger time at 2023-06-16 07:20:50 UT, with upper limit up to 16.9 mag. The observations began at zenith distance = 35 deg. The sun altitude is -52.6 deg.
The galactic latitude b = -5 deg., longitude l = 36 deg.
