MASTER-Amur robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Blagoveshchensk State Pedagogical University) started inspect of the Fermi GRB191008.3 (trigger No 592211224,03h 22m 36.000s , +47d 19m 48.00s, R=11.9) errorbox  26779 sec after trigger time at 2019-10-08 14:33:18 UT, with upper limit up to  17.8 mag. The observations began at zenit distance = 25 deg. The sun  altitude  is -44.8 deg. 

The galactic latitude b = -60 deg., longitude l = 98 deg.


Real time updated cover map and OT discovered available here:
