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 201007.92 (trigger No 31638233,17h 40m 13.92s , +05d 22m 55.2s, R=0.51) errorbox  6125 sec after notice time and 6243 sec after trigger time at 2020-10-07 23:45:52 UT, with upper limit up to  18.5 mag. Observations started at twilight.  The observations began at zenith distance = 52 deg. The sun  altitude  is -14.5 deg. 

The galactic latitude b = 18 deg., longitude l = 30 deg.
