MASTER-Tunka robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Applied Physics Institute, Irkutsk State University) started inspect of the Fermi GRB201008.75 (trigger No 623873165,06h 12m 38.40s , +38d 27m 00.0s, R=3.1) errorbox  92 sec after notice time and 181 sec after trigger time at 2020-10-08 18:09:02 UT, with upper limit up to  14.2 mag. The observations began at zenith distance = 43 deg. The sun  altitude  is -42.5 deg. 

The galactic latitude b = 10 deg., longitude l = 175 deg.


Real time updated cover map and OT discovered available here:
