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 190629.56 (  1h 39m 36.00s , +25d 48m 00.00s, R=3) errorbox  29845 sec after trigger time at 2019-06-29 21:41:16 UT, with upper limit up to  17.1 mag. The observations began at zenit distance = 84 deg. The sun  altitude  is -22.8 deg. 

The galactic latitude b = -60 deg., longitude l = 98 deg.
