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) started inspect of the Baksan Neutrino Observatory Alert 201022.66 (trigger No 1654098938,06h 36m 48.00s , +35d 42m 00.0s, R=3) errorbox  7683 sec after notice time and 8262 sec after trigger time at 2020-10-22 18:13:20 UT, with upper limit up to  17.6 mag. The observations began at zenith distance = 80 deg. The sun  altitude  is -37.1 deg. 

The galactic latitude b = 13 deg., longitude l = 179 deg.
