MASTER-SAAO robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in South Africa (South African Astronomical Observatory) started inspect of the Baksan Neutrino Observatory Alert 201006.88 (trigger No 1652734969,18h 52m 00.00s , -62d 12m 00.0s, R=3) errorbox  5 sec after notice time and 1130 sec after trigger time at 2020-10-06 21:21:40 UT, with upper limit up to  19.5 mag. The observations began at zenith distance = 55 deg. The sun  altitude  is -49.5 deg. 

The galactic latitude b = -24 deg., longitude l = 334 deg.
