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) was pointed to the Swift GRB191115.48 (trigger No 937114,19h 28m 42.96s , +38d 43m 48.0s, R=0.05) errorbox 43 sec after trigger time at 2019-11-15 11:27:04 UT, with upper limit up to 16.2 mag. The observations began at zenith distance = 44 deg. The sun altitude is -35.0 deg. The galactic latitude b = 10 deg., longitude l = 72 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1196549 We obtain a following upper limits.
