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 GRB191015.33 (trigger No 592818648,12h 25m 38.400s , +21d 31m 48.00s, R=7.23) errorbox 45574 sec after trigger time at 2019-10-15 20:30:18 UT, with upper limit up to 16.8 mag. Observations started at twilight. The observations began at zenit distance = 68 deg. The sun altitude is -14.0 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=1167136 We obtain a following upper limits.
