MASTER-Tunka robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Applied Physics Institute, Irkutsk State University) started inspect of the Baksan Neutrino Observatory Alert 200617.47 (trigger No 1643109675,22h 46m 24.00s , +30d 36m 00.0s, R=3) errorbox  13121 sec after notice time and 13974 sec after trigger time at 2020-06-17 15:14:09 UT, with upper limit up to  18.0 mag. Observations started at twilight.  The observations began at zenith distance = 72 deg. The sun  altitude  is -11.5 deg. 

The galactic latitude b = -25 deg., longitude l = 94 deg.
