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 IceCube Alert 190704.78 ( 10h 45m 37.92s , +27d 25m 08.40s, R=0.85) errorbox  7623 sec after trigger time at 2019-07-04 20:55:55 UT, with upper limit up to  18.0 mag. Observations started at twilight.  The observations began at zenit distance = 52 deg. The sun  altitude  is -10.9 deg. 

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