Sergienko (Blagoveschensk Educational State University) 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 201115.09 (trigger No 70289682,12h 55m 01.92s , +01d 17m 24.0s, R=0.51) errorbox 1 days 10999 sec after notice time and 1 days 11121 sec after trigger time at 2020-11-16 05:12:47 UT, with upper limit up to 16.9 mag. The observations began at zenith distance = 77 deg. The sun altitude is -29.2 deg. The galactic latitude b = 64 deg., longitude l = 306 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1482363 We obtain a following upper limits.
