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 GRB191105.01 (trigger No 933276,19h 34m 58.320s , +21d 54m 54.00s, R=0.05) errorbox  34 sec after notice time and 57 sec after trigger time at 2019-11-05 00:09:55 UT, with upper limit up to  15.6 mag. The observations began at zenith distance = 86 deg. The sun  altitude  is -74.9 deg. 

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