Sergienko (Blagoveschensk Educational State University) MASTER-OAFA robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Argentina (OAFA observatory of San Juan National University) started inspect of the Fermi GRB190719.11 (trigger No 585196946, 8h 15m 43.20s , -30d 48m 36.00s, R=5.22) errorbox 28512 sec after trigger time at 2019-07-19 10:37:33 UT, with upper limit up to 17.2 mag. Observations started at twilight. The observations began at zenit distance = 75 deg. The sun altitude is -11.3 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=1078756 We obtain a following upper limits.
