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 S230529ay errorbox 35464 sec after notice time and 35512 sec after trigger time at 2023-05-30 04:06:52 UT, with upper limit up to 20.0 mag. The observations began at zenith distance = 44 deg. The sun altitude is -79.1 deg.
The galactic latitude b = 10 deg., longitude l = 351 deg.
Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/ligo_1.php?id=11912
We obtain a following upper limits.
