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 191127.25 (trigger No 1625551366,01h 14m 00.00s , +11d 48m 00.0s, R=3) errorbox 1249 sec after trigger time at 2019-11-27 06:23:35 UT, with upper limit up to 17.2 mag. The observations began at zenith distance = 83 deg. The sun altitude is -30.4 deg.
MASTER-Amur robotic telescope located in Russia (Blagoveshchensk State Pedagogical University) started inspect of the Baksan Neutrino Observatory Alert 191127.25 errorbox 9627 sec after trigger time at 2019-11-27 08:43:13 UT, with upper limit up to 17.4 mag. Observations started at twilight. The observations began at zenith distance = 59 deg. The sun altitude is -10.6 deg.
The galactic latitude b = -50 deg., longitude l = 133 deg.
