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 200408.26 (trigger No 1637043236,14h 10m 48.00s , +15d 36m 00.0s, R=3) errorbox  1 days 44298 sec after notice time and 1 days 44667 sec after trigger time at 2020-04-09 18:38:23 UT, with upper limit up to  17.7 mag. The observations began at zenith distance = 54 deg. The sun  altitude  is -23.3 deg. 

MASTER-SAAO robotic telescope  located in South Africa (South African Astronomical Observatory) started inspect of the Baksan Neutrino Observatory Alert 200408.26 errorbox  1 days 59907 sec after notice time and 1 days 60277 sec after trigger time at 2020-04-09 22:58:32 UT, with upper limit up to  16.0 mag. The observations began at zenith distance = 53 deg. The sun  altitude  is -65.5 deg. 

The galactic latitude b = 68 deg., longitude l =  5 deg.
