MASTER-SAAO robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in South Africa (South African Astronomical Observatory) started inspect of the Fermi GRB190703.57 (trigger No 583854113, 15h  1m 40.08s , +33d 49m 01.20s, R=50) errorbox  10752 sec after trigger time at 2019-07-03 16:41:00 UT, with upper limit up to  19.0 mag. Observations started at twilight.  The observations began at zenit distance = 73 deg. The sun  altitude  is -11.5 deg. 

The galactic latitude b = -60 deg., longitude l = 98 deg.
