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 GRB191001.28 (trigger No 591604915,20h 35m 02.400s , +15d 16m 48.00s, R=2.65) errorbox  13621 sec after trigger time at 2019-10-01 10:28:51 UT, with upper limit up to  17.9 mag. Observations started at twilight.  The observations began at zenit distance = 38 deg. The sun  altitude  is -13.2 deg. 

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