MASTER-Kislovodsk robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) was pointed to the IceCube Alert 221124.66 (trigger No 24212476,19h 55m 43.68s , +03d 28m 48.0s, R=0.9) errorbox  6 sec after notice time and 53 sec after trigger time at 2022-11-24 15:46:55 UT, with upper limit up to  15.8 mag. The observations began at zenith distance = 55 deg. The sun  altitude  is -22.7 deg. 

The galactic latitude b = -13 deg., longitude l = 44 deg.
