MASTER-OAFA robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Argentina (OAFA observatory of San Juan National University) started inspect of the Baksan Neutrino Observatory Alert 200905.99 (trigger No 1650067106,09h 21m 12.00s , -55d 48m 00.0s, R=3) errorbox  22 sec after notice time and 424 sec after trigger time at 2020-09-06 00:05:30 UT, with upper limit up to  16.2 mag. The observations began at zenith distance = 87 deg. The sun  altitude  is -23.0 deg. 

The galactic latitude b = -4 deg., longitude l = 277 deg.


Real time updated cover map and OT discovered available here:
