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 S230614t errorbox 30018 sec after notice time and 30070 sec after trigger time at 2023-06-14 22:37:32 UT, with upper limit up to 14.6 mag. Observations started at twilight. The observations began at zenith distance = 69 deg. The sun altitude is -12.3 deg.
The galactic latitude b = -1 deg., longitude l = 224 deg.
Real time updated cover map and OT discovered available here:
