MASTER-OAFA robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Argentina (OAFA observatory of San Juan National University) was pointed to the Integral GRB190919.99 (trigger No 8377,20h 48m 58.080s , -44d 38m 49.20s, R=0.0505) errorbox  26 sec after trigger time at 2019-09-19 23:47:17 UT, with upper limit up to  19.6 mag. The observations began at zenit distance = 24 deg. The sun  altitude  is -17.5 deg. 

MASTER-IAC robotic telescope  located in Spain (IAC Teide Observatory) was pointed to the Integral GRB190919.99 errorbox  32 sec after trigger time at 2019-09-19 23:47:23 UT, with upper limit up to  19.0 mag. The observations began at zenit distance = 77 deg. The sun  altitude  is -56.2 deg. 

MASTER-SAAO robotic telescope  located in South Africa (South African Astronomical Observatory) was pointed to the Integral GRB190919.99 errorbox  54 sec after trigger time at 2019-09-19 23:47:45 UT, with upper limit up to  16.4 mag. The observations began at zenit distance = 50 deg. The sun  altitude  is -54.7 deg. 

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