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 S190728q errorbox 16 sec after notice time and 919 sec after trigger time at 2019-07-28 07:00:29 UT, with upper limit up to 18.1 mag. The observations began at zenit distance = 57 deg. The sun altitude is -56.5 deg.
The galactic latitude b = -60 deg., longitude l = 98 deg.
Real time updated cover map and OT discovered available here:
