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 200819.09 (trigger No 1648520072,16h 13m 12.00s , -01d 18m 00.0s, R=3) errorbox 353 sec after notice time and 685 sec after trigger time at 2020-08-19 02:25:57 UT, with upper limit up to 18.7 mag. The observations began at zenith distance = 57 deg. The sun altitude is -54.5 deg.
The galactic latitude b = 33 deg., longitude l = 11 deg.
