MASTER-SAAO robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in South Africa (South African Astronomical Observatory) was pointed to the IceCube Alert 201115.67 (trigger No 49508272,09h 55m 00.48s , -21d 38m 31.2s, R=0.86) errorbox  1 days 26427 sec after notice time and 1 days 26477 sec after trigger time at 2020-11-16 23:23:00 UT, with upper limit up to  18.5 mag. The observations began at zenith distance = 73 deg. The sun  altitude  is -37.1 deg. 

The galactic latitude b = 25 deg., longitude l = 258 deg.
