LIGO/Virgo S230619as: 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 S230619as errorbox 38538 sec after notice time and 38633 sec after trigger time at 2023-06-19 22:40:12 UT, with upper limit up to 17.2 mag. Observations started at twilight. The observations began at zenith distance = 66 deg. The sun altitude is -12.7 deg. The galactic latitude b = 27 deg., longitude l = 285 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/ligo_1.php?id=12154 We obtain a following upper limits.
