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 Fermi GRB201105.23 (trigger No 626247072,16h 18m 00.00s , +16d 02m 24.0s, R=1) errorbox  70707 sec after notice time and 1 days 35703 sec after trigger time at 2020-11-06 15:26:11 UT, with upper limit up to  17.0 mag. Observations started at twilight.  The observations began at zenith distance = 62 deg. The sun  altitude  is -11.1 deg. 

The galactic latitude b = 41 deg., longitude l = 31 deg.
