LIGO/Virgo S230618y: Global MASTER-Net observations report
Abstract
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 S230618y errorbox 48813 sec after notice time and 48871 sec after trigger time at 2023-06-19 00:00:21 UT, with upper limit up to 14.4 mag. The observations began at zenith distance = 71 deg. The sun altitude is -29.2 deg. The galactic latitude b = 28 deg., longitude l = 268 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/ligo_1.php?id=12110 We obtain a following upper limits.
