LIGO/Virgo/KAGRA S230627c: Global MASTER-Net observations report
Abstract
MASTER-OAGH robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Mexico (OAGH National Institute for Astrophysics, Optics and Electronics) started inspect of the LIGO/Virgo/KAGRA S230627c errorbox 15958 sec after notice time and 16028 sec after trigger time at 2023-06-27 06:20:45 UT, with upper limit up to 16.4 mag. The observations began at zenith distance = 65 deg. The sun altitude is -33.7 deg. The galactic latitude b = 58 deg., longitude l = 164 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/ligo_1.php?id=12441 We obtain a following upper limits.
