MASTER-Amur robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Blagoveshchensk State Pedagogical University) was pointed to the IceCube Alert 200117.46 (trigger No 1410505,07h 43m 50.64s , +29d 19m 12.0s, R=0.51) errorbox  12 sec after notice time and 69 sec after trigger time at 2020-01-17 11:09:39 UT, with upper limit up to  18.2 mag. The observations began at zenith distance = 52 deg. The sun  altitude  is -30.0 deg. 

The galactic latitude b = 24 deg., longitude l = 191 deg.
