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 S190829u errorbox 44 sec after trigger time at 2019-08-29 21:06:40 UT, with upper limit up to 19.0 mag. The observations began at zenit distance = 75 deg. The sun altitude is -21.6 deg.
MASTER-SAAO robotic telescope located in South Africa (South African Astronomical Observatory) started inspect of the LIGO/Virgo S190829u errorbox 30 sec after notice time and 472 sec after trigger time at 2019-08-29 21:13:48 UT, with upper limit up to 19.7 mag. The observations began at zenit distance = 42 deg. The sun altitude is -59.8 deg.
The galactic latitude b = -60 deg., longitude l = 98 deg.
