MASTER-IAC robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Spain (IAC Teide Observatory) started inspect of the LIGO/Virgo S190510g errorbox 5366 sec after trigger time at 2019-05-10 04:29:05 UT, with upper limit up to 19.4 mag. The observations began at zenit distance = 82 deg. The sun altitude is -21.9 deg.
MASTER-OAFA robotic telescope located in Argentina (OAFA observatory of San Juan National University) started inspect of the LIGO/Virgo S190510g errorbox 5771 sec after trigger time at 2019-05-10 04:35:50 UT, with upper limit up to 19.5 mag. The observations began at zenit distance = 125 deg. The sun altitude is -76.4 deg.
The galactic latitude b = -60 deg., longitude l = 98 deg.
