LIGO/Virgo S230616j: 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 S230616j errorbox 10 sec after notice time and 139 sec after trigger time at 2023-06-16 04:26:33 UT, with upper limit up to 19.2 mag. The observations began at zenith distance = 71 deg. The sun altitude is -82.1 deg. The galactic latitude b = -56 deg., longitude l = 240 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/ligo_1.php?id=12062 We obtain a following upper limits.
