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 201120.43 (trigger No 1656584036,06h 46m 24.00s , +38d 12m 00.0s, R=3) errorbox  24156 sec after notice time and 24526 sec after trigger time at 2020-11-20 17:02:43 UT, with upper limit up to  17.7 mag. The observations began at zenith distance = 76 deg. The sun  altitude  is -30.4 deg. 

The galactic latitude b = 16 deg., longitude l = 178 deg.
