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 GRB190710.65 (trigger No 584465880, 11h 17m 04.08s , -50d  9m 00.00s, R=50) errorbox  13988 sec after trigger time at 2019-07-10 19:31:03 UT, with upper limit up to  19.7 mag. The observations began at zenit distance = 55 deg. The sun  altitude  is -46.3 deg. 

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