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  GRB191105.01 38 sec after notice time and 57 sec after trigger time at 2019-11-05 00:09:55 UT. On our 3-th (30s exposure)  set , obtained 134 sec after tigger time at 2019-11-05 00:11:13 UT, we  found 1 optical transient within Swift error-box (ra=293.742 dec=21.9147 r=0.05) brighter than 14.22.
