MASTER-IAC robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Spain (IAC Teide Observatory) was pointed to the Swift GRB191011.19 (trigger No 928924,02h 58m 53.640s , -27d 50m 41.28s, R=0.05) errorbox  67 sec after trigger time at 2019-10-11 04:37:04 UT, with upper limit up to  20.0 mag. The observations began at zenit distance = 62 deg. The sun  altitude  is -32.4 deg. 

MASTER-OAFA robotic telescope  located in Argentina (OAFA observatory of San Juan National University) was pointed to the Swift GRB191011.19 errorbox  85 sec after trigger time at 2019-10-11 04:37:21 UT, with upper limit up to  18.3 mag. The observations began at zenit distance = 21 deg. The sun  altitude  is -52.0 deg. 

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