MASTER-OAFA robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Argentina (OAFA observatory of San Juan National University) was pointed to the IceCube Alert 200916.86 (trigger No 12605830,07h 17m 36.48s , +14d 20m 56.4s, R=0.66) errorbox  39362 sec after notice time and 39399 sec after trigger time at 2020-09-17 07:37:10 UT, with upper limit up to  17.6 mag. The observations began at zenith distance = 78 deg. The sun  altitude  is -37.2 deg. 

The galactic latitude b = 13 deg., longitude l = 203 deg.
