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 200410.97 (trigger No 24635982,16h 05m 03.84s , +11d 35m 06.0s, R=0.53) errorbox  20 sec after notice time and 73 sec after trigger time at 2020-04-10 23:21:08 UT, with upper limit up to  18.1 mag. The observations began at zenith distance = 33 deg. The sun  altitude  is -30.9 deg. 

MASTER-Tavrida robotic telescope  located in Russia (Lomonosov MSU, SAI Crimea astronomical station) was pointed to the IceCube Alert 200410.97 errorbox  38 sec after notice time and 90 sec after trigger time at 2020-04-10 23:21:26 UT, with upper limit up to  17.6 mag. The observations began at zenith distance = 36 deg. The sun  altitude  is -33.2 deg. 

The galactic latitude b = 42 deg., longitude l = 24 deg.
