Sergienko (Blagoveschensk Educational State University) 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 GRB191104.39 (trigger No 594551878,19h 24m 26.400s , +25d 16m 48.00s, R=4.4) errorbox 156 sec after notice time and 223 sec after trigger time at 2019-11-04 09:21:36 UT, with upper limit up to 12.4 mag. Observations started at twilight. The observations began at zenith distance = 30 deg. The sun altitude is -12.8 deg. The galactic latitude b = -60 deg., longitude l = 98 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1186793 We obtain a following upper limits.
