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 GRB201011.63 (trigger No 624121589,18h 44m 12.00s , -05d 43m 12.0s, R=2.38) errorbox  7808 sec after notice time and 7854 sec after trigger time at 2020-10-11 17:17:19 UT, with upper limit up to  17.0 mag. The observations began at zenith distance = 58 deg. The sun  altitude  is -24.3 deg. 

The galactic latitude b = -2 deg., longitude l = 27 deg.
