MASTER-Tavrida robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Lomonosov MSU, SAI Crimea astronomical station) was pointed to the IceCube Alert 201124.34 (trigger No 68186,08h 59m 57.60s , +07d 44m 24.0s, R=0.5) errorbox  31682 sec after notice time and 54964 sec after trigger time at 2020-11-24 23:30:51 UT, with upper limit up to  15.8 mag. The observations began at zenith distance = 52 deg. The sun  altitude  is -55.8 deg. 

The galactic latitude b = 33 deg., longitude l = 222 deg.
