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 GRB190916.59 (trigger No 590335819,21h 25m 04.800s , -48d 54m 00.00s, R=11.78) errorbox  41708 sec after trigger time at 2019-09-17 01:45:22 UT, with upper limit up to  18.7 mag. The observations began at zenit distance = 67 deg. The sun  altitude  is -36.2 deg. 

MASTER-OAFA robotic telescope  located in Argentina (OAFA observatory of San Juan National University) started inspect of the Fermi GRB190916.59 errorbox  43286 sec after trigger time at 2019-09-17 02:11:40 UT, with upper limit up to  18.2 mag. The observations began at zenit distance = 18 deg. The sun  altitude  is -46.7 deg. 

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