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 GRB190429.74 ( 13h 20m 12.00s , - 8d  0m 00.00s, R=8) errorbox  2251 sec after trigger time at 2019-04-29 18:27:21 UT, with upper limit up to  19.5 mag. The observations began at zenit distance = 49 deg. The sun  altitude  is -31.0 deg. 

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