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 GRB190712.09 (trigger No 584590606, 19h 13m 33.60s , +56d 9m 00.00s, R=7.59) errorbox 502 sec after notice time and 532 sec after trigger time at 2019-07-12 02:25:33 UT, with upper limit up to 18.9 mag. The observations began at zenit distance = 32 deg. The sun altitude is -36.6 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=1072676 We obtain a following upper limits.
