MASTER-IAC robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Spain (IAC Teide Observatory) started inspect of the Fermi GRB201011.84 (trigger No 624139481,19h 22m 52.80s , -11d 27m 00.0s, R=9.59) errorbox  84 sec after notice time and 146 sec after trigger time at 2020-10-11 20:07:03 UT, with upper limit up to  17.7 mag. The observations began at zenith distance = 35 deg. The sun  altitude  is -20.5 deg. 

The galactic latitude b = -13 deg., longitude l = 27 deg.


Real time updated cover map and OT discovered available here:
