LIGO/Virgo S230618at: 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 S230618at errorbox 31514 sec after notice time and 31657 sec after trigger time at 2023-06-19 02:45:19 UT, with upper limit up to 12.8 mag. The observations began at zenith distance = 37 deg. The sun altitude is -64.4 deg. The galactic latitude b = 3 deg., longitude l = 341 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/ligo_1.php?id=12122 We obtain a following upper limits.
