LIGO/Virgo S200219ac: Global MASTER-Net observations report
Abstract
MASTER-Amur robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Blagoveshchensk State Pedagogical University) started inspect of the LIGO/Virgo S200219ac errorbox 101 sec after notice time and 9677 sec after trigger time at 2020-02-19 12:25:32 UT, with upper limit up to 17.2 mag. The observations began at zenith distance = 53 deg. The sun altitude is -34.0 deg. The galactic latitude b = -84 deg., longitude l = 224 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/ligo_1.php?id=11346 We obtain a following upper limits.
