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 GRB190705.34 (trigger No 584007338,  5h 53m 00.00s , -25d 43m 01.20s, R=25.85) errorbox  30804 sec after trigger time at 2019-07-05 16:48:57 UT, with upper limit up to  18.6 mag. Observations started at twilight.  The observations began at zenit distance = 90 deg. The sun  altitude  is -13.0 deg. 

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