Sergienko (Blagoveschensk Educational State University) MASTER-IAC robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Spain (IAC Teide Observatory) started inspect of the Fermi GRB201119.02 (trigger No 627438255,07h 48m 50.40s , +32d 10m 48.0s, R=27.3) errorbox 6329 sec after notice time and 6382 sec after trigger time at 2020-11-19 02:10:32 UT, with upper limit up to 18.5 mag. The observations began at zenith distance = 35 deg. The sun altitude is -69.4 deg. The galactic latitude b = 26 deg., longitude l = 189 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1485204 We obtain a following upper limits.
