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 GRB190813.52 (trigger No 587392154,  7h  8m 40.80s , -21d  8m 24.00s, R=8.4) errorbox  48320 sec after trigger time at 2019-08-14 01:54:29 UT, with upper limit up to  17.7 mag. The observations began at zenit distance = 75 deg. The sun  altitude  is -43.3 deg. 

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