MASTER-SAAO robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in South Africa (South African Astronomical Observatory) started inspect of the Baksan Neutrino Observatory Alert 201230.40 (trigger No 1660038178,11h 51m 36.00s , -41d 24m 00.0s, R=3) errorbox 41047 sec after notice time and 41443 sec after trigger time at 2020-12-30 21:13:41 UT, with upper limit up to 17.2 mag. The observations began at zenith distance = 74 deg. The sun altitude is -31.0 deg.
The galactic latitude b = 20 deg., longitude l = 292 deg.
Real time updated cover map and OT discovered available here:
